The German air defense system mistakenly shot the U.S. UAV, and the identification of friend or foe is still the core problem in the battlefield.

According to a number of foreign media reports, on February 26th, the German F-124 "Saxony" class frigate "Hessen", which was on a combat escort mission in the Red Sea, fired two "Standard-2" (SM-2) air defense missiles at a target that failed to confirm its identity and was judged as a "reconnaissance drone".

Due to technical reasons that did not disclose details, the missile failed and crashed into the sea.

F-124 frigate launches SM-2 missile.

Afterwards, it was proved that the targeted drone was an American MQ-9 "Death" drone that was carrying out a strike mission against Houthi armed targets nearby. The series of related news was confirmed by German Defense Ministry spokesman Michael Steinfler on February 28th.

However, the spokesman stressed that "Hesse" had carried out a complete identification process before firing, including radio response, and asked the allies whether there were drones performing tasks in the airspace.

MQ-9 UAV

In addition, the failure of two SM-2 missiles has also caused waves in Germany.

Lack of air defense equipment in Germany

A spokesman for the German Federal Parliament’s national defense policy said, "We have only now learned according to the requirements that some ammunition of the frigate Hessen can no longer be purchased because it no longer has the corresponding industrial capacity. When the stocks are exhausted, the German navy can no longer replenish them and must withdraw the frigates. " In addition, he also accused the current German government of concealing the truth from the opposition party, which led to the parliament’s unwitting decision to send frigates to participate in escort operations.

The F-124 frigate takes air defense as its main task, and is equipped with advanced multi-function radar and various air defense weapons, including SM-2 Block IIIA, Evolution Sea Sparrow (ESSM) and RIM-116. SM-2 BlockIIIA suffered the ammunition inventory crisis. According to the disclosure of information about this accidental attack by the German Ministry of Defence, the ammunition has been discontinued.

SM-2 series missiles were designed earlier. SM-2 Block1 was developed in 1970s, and its production line was closed in 2013 due to lack of orders.

After the Crimean incident in 2014, the global demand for SM-2 soared. Raytheon restarted its production line in 2017 to meet the demand of more than 280 SM-2 BlockIIIA/B in the Netherlands, Japan, Australia, South Korea and other countries, and announced that the production line will be maintained until 2035. In 2021, Chile made a purchase demand for SM-2 BlockIIIA to the United States, but the quantity was very small.

At present, the latest model of SM-2 series is SM-2 BlockIIIC, which is in the initial production stage of low speed. The missile has undergone a major technical upgrade and completely changed its guidance system: SM-2 BlockIIIA uses inertial navigation, radio command correction and semi-active radar composite guidance; SM-2 BlockIIIB replaces the seeker with the dual-mode system of infrared imaging and semi-active radar on the basis of Type A; SM-2 BlockIIIC is replaced by an active radar guided seeker, which comes from the "Standard -6" extended range active missile (SM-6 ERAM).

Although SM-2 BlockIIIC has been significantly enhanced in performance, it can effectively fight against high-mobility and high-agility targets and has the ability to attack targets outside the radar detection range of warships; However, the change of guidance mode and other improvements make it incompatible with the mission management and fire control system of the existing F-124 frigate.

This also means that once the existing SM-2 BlockIIIA runs out of stocks, Germany not only needs to order SM-2 BlockIIIC missiles with a long production cycle from the United States, but also needs to carry out targeted shipboard equipment improvement and certification tests for F-124 frigates. The time required for this process may be calculated in years.

Predicament of friend-or-foe identification in UAV era

Compared with the missile inventory crisis, which mainly stems from Germany’s own political struggle and management system problems, the wartime friend-or-foe identification problem once again displayed in this accidental attack is a dilemma that all countries are facing. Especially in the era of drones, this problem is becoming more and more difficult.

Friend or foe identification transponder

From a purely technical point of view, many countries have developed a large number of IFF technologies, including cooperative and uncooperative. When the two sides interact and cooperate, they can complete the identification by means of wireless communication through the principle of "inquiry/reply"; When the target is in a non-cooperative state, the inquirer will summarize and fuse all the collected target information (radar echo signal, infrared radiation, acoustic signal, GPS information) and implement compulsory identification.

In the ideal technical test environment, it is possible to realize fast and accurate identification of friend or foe by relying on the complementary combination of these two means. However, in the actual combat environment, many factors, such as political intervention, the setting of rules of engagement, and the management system of military tasks, may completely lead to the unreliability of the existing methods of identifying the enemy or ourselves. The incident in which a German frigate accidentally attacked an American drone is a typical example.

Failure reasons of collaborative identification:

For some reason not publicly disclosed by the US, the targeted MQ-9 failed to turn on the IFF transponder, or the related equipment failed, and the German frigate recognized it as a non-friendly target without an effective response.

Failure reasons of non-cooperative identification level:

Due to the differences of interests between different countries and departments, Europe and the United States have several military operations in the Red Sea and the surrounding areas of Yemen, which are not subordinate to each other and lack a unified command and coordination structure. Due to the confidentiality requirements of military operations, it is very common for different units to be unaware of the existence of the other side, even in the army of the same country.

The Hessian frigate participated in the "Aspad" escort operation led by the European Union, while the escort mission of the US military was the earlier "Guardian of Prosperity" operation. The mistakenly attacked MQ-9 is not affiliated with the "Prosperity Guardian", but another US military operation whose name is unknown at present. The US military units participating in the "Prosperity Guardian" operation are unaware of the existence of the MQ-9 drone.

This led to the "Hesse" frigate, although it initiated consultation with the American unit responsible for the "Guardian of Prosperity", but it got the wrong answer. In the airspace where the target signal is located, the real situation is only that "there is no aircraft participating in the prosperity guardian operation", not "there is no aircraft of the US military".

The 40-kilogram unmanned aerial vehicle (UAV) appeared on the battlefield in Ukraine, with a unit price of up to $15,000. It is not worth the loss to carry the traditional IFF transponder.

Compared with purely technical problems, these non-technical factors often make it more difficult to identify the friend or foe. Especially from the actual combat environment such as Ukraine and Yemen in recent years, the identification of friend or foe of drones will become more and more troublesome. The popularity of small and medium-sized UAVs and the extensive participation of civilian UAVs in military operations inevitably bring more problems, such as the following:

01For reasons such as economy and confidentiality risks, a large number of UAVs participating in the war are not equipped with IFF equipment at all.

02At the same time, the number of units operating drones on the battlefield is unprecedented, and the task information between them is not interoperable.

03A large number of unmanned aerial vehicles (especially multi-rotor aircraft) are highly similar in design, and a large number of key features are highly similar from appearance shape to acoustic signals, lacking effective means of distinction; Or both sides are equipped with a large number of equipment at the same time (more common in civilian models), and it is meaningless to distinguish models.

Undoubtedly, drones will further play a more important role in the future battlefield; How to deal with the corresponding friend or foe identification problem will be an extremely critical research topic.

Is a muscular man necessarily healthy? Have you been shot in these fitness "misunderstandings"?

   Swimming can also swim out of the swimming shoulder?

  Is a muscular man necessarily healthy?

  Can you jump out of the disease by dancing square dance?

  Which sports are the elderly suitable for?

  Around the hot topic of netizens,

  The reporter interviewed Dr. Wu Liang, director of the Rehabilitation Center of Xiaotangshan Hospital in Beijing.

  Let him talk about how much you jumped in these common fitness pits.

  First, swimming

  Summer is hot,Many sportsmen choose to move to the swimming pool.,

  Swimming is not only a good way to cool off the heat.,

  It can also enhance cardiopulmonary function and exercise physical flexibility.,You can also lose weight and burn fat.

  But some people are getting harder and harder when paddling.,

  At this time, we should pay attention to the "swimming shoulder".

  What is a "swimming shoulder"?

  Shoulder injury caused by excessive shoulder movement during swimming is scientifically called "Shoulder Impact Syndrome", which includes glenoid lip structure injury, tendon injury (biceps brachii and tendon of long head) and related soft tissue injury. Swimming shoulder is the injury with the highest incidence in swimming events.

  Why do some people get "swimming shoulders"?

  Abnormal movements, excessive swimming training, improper use of swimming training tools, shoulder joint relaxation and weakened shoulder muscle strength are all important factors that cause swimming shoulder.

  How to prevent "swimming shoulders"?

  First, strengthen the strength and improve the stability of the shoulder. Prepare fully for activities, such as bending your head forward and rotating your back 10 ~ 15 times to move your neck; Shoulders shrug, arms draw circles and do chest expansion exercises for 10 ~ 15 times each to move shoulders and chest; Bend your knees, bend your hips, do squats and stand up alternately for 10 ~ 15 times each to move your knees.

  The second is to maintain the correct posture, the body is in a flat state, the body is relaxed, the movements are stretched, the hand and foot movements are coordinated in place, and the swimming speed is balanced. It is not advisable to be too fast and too hard.

  The third is to control the time reasonably, and the swimming time should not be too long, no more than one hour at a time.

  Fourth, adapt to the temperature of the pool water in advance. Before entering the water, swimmers should wet their limbs, chest, abdomen and back with cold water at the edge of the pool or on the shore, so as to gradually adapt to the temperature in the water, which can effectively avoid the occurrence of swimming deformation and cramping.

  Everyone knows that swimming has a positive effect on the exercise of lumbar, cervical and back muscles and cardiopulmonary function. However, whether you are a swimmer or a novice, you should swim slowly to avoid suffering from "swimming shoulders".  

  Second, fitness

  Mention people who do fitness.,

  Many people usually think of sunny men who are healthy and full of spirit.

  Biceps brachii and eight-pack abdominal muscles … …

  Body-building muscles make men more attractive.,

  so

  Is a muscular man necessarily healthy?

  Muscular men can be divided into five types: capable, lean, thick, fat and rocky, and do not refer to bodybuilders whose muscles are as hard as rocks. The first three kinds pay attention to the coordinated training of muscles, which makes us pursue healthy and beautiful training results, while the latter two kinds should be avoided as much as possible. Excessive emphasis on the transitional training of some muscles will not only cause muscle joint injury, but also cause abnormal development of human body.

  In order to pursue muscle and increase the intake of protein, the diet structure will be destroyed, which will lead to the lack of nutrition in other organs and systems of the human body, resulting in the impairment of its function. Moreover, excessive muscle exercise will increase the load on the heart and consume more oxygen; More blood is distributed to the muscles; Thereby reducing the blood supply to other tissues. Scientific and reasonable diet, proper exercise and coordinated and balanced development are the real health and beauty.

  Third, yoga

  Yoga because "no threshold",

  Is being loved by more and more people.

  Is yoga really suitable for everyone?

  First of all, you should be familiar with all parts of your body, so that you can exert yourself correctly during the practice. Secondly, you should know whether you have diseases such as high blood pressure and heart disease, or whether you have injuries to cervical vertebrae and lumbar vertebrae, and the injury history of other parts of your body, and avoid doing actions that may cause damage to your body.

  Furthermore, beginners should avoid practicing yoga alone. They should choose a yoga teacher with professional qualification certificate to guide them, and choose appropriate courses. When practicing, they should wear soft and comfortable yoga clothes and equip them with professional props, such as yoga blankets and bricks, so as to better protect and support their bodies. Finally, the practitioner should fully warm up before practice, and stop immediately if he feels uncomfortable.

  The following groups of people need to pay special attention when practicing yoga: 1. People who are physically weak or have high blood pressure, cardiovascular and cerebrovascular diseases and respiratory diseases should pay attention to cultivating their hearts when practicing yoga, and remember not to pursue the amplitude and intensity of movements. Because excessive flexion, extension and rotation can compress the abdomen and lower limbs, increase abdominal pressure, increase venous blood in the heart, increase heart load, and lead to dyspnea or recurrence of old diseases.

  2. Children should pay special attention to practicing yoga. Although practicing yoga can enhance the flexibility of muscles and ligaments, improper practice of yoga in children with developing bones and soft tissues is likely to cause injuries and sequelae, and even affect their physical development.

  Fourth, square dance

   Whether it’s a street or an alley.,

  The middle-aged and elderly people dancing in the square dance at night can be described as a great landscape.,

  Has become a social phenomenon.

  The role of square dance in fitness and entertainment is self-evident.,

  What should I pay attention to when dancing?

  Square dance will also jump out of illness?

  In terms of time, many square dances now basically take about an hour. Older people should do it step by step and according to their abilities. They should come gradually and stop as soon as they feel uncomfortable. Some movements should not be forced to be in place. Don’t blindly compare movements and dance with each other.

  From the action, don’t blindly pursue the unity of the whole action, but pursue the difference of everyone. For example, people with low back pain and osteoarthritis should try to avoid twisting, bending and excessive squatting, otherwise it will increase the damage to the waist and joints. If you have a good foundation for long-term exercise, you can do what you can according to your own situation.

  What diseases can’t people jump? People suffering from coronary heart disease, osteoarthritis, cervical disc herniation, and lumbar disc herniation, it is best to consult relevant specialists to understand the exercise methods suitable for them.

  so,

  Speaking of which, are you confused?,

  Don’t worry.,

  Pay attention to the following principles for the elderly.

  First of all, we should pay attention to the principle of interest. The old man’s interests, hobbies and habits determine his actions and activities. Therefore, when making exercise prescriptions, the principle of interest should be put in the first place.

  The second principle of individuality, is the body suitable for exercise? When and what kind of sports will cause further damage, and what diseases are there? This is to be evaluated when choosing a mode of exercise. Our fitness suggestions for the elderly can be summarized by several key words, "long-term, classic, aerobic and outdoor". What is long-term and classic? Quite simply, it is the track events of the Olympic Games, such as walking, running, swimming and cycling.

  Third, step by step, remember to do what you can. Don’t think one thing a day. If yoga is popular today, you can practice it. If hip-hop is popular tomorrow, you can dance hip-hop and run the day after tomorrow.

  For example, you can choose to walk slowly at first, then slowly start jogging, and if possible, you can ride a bike and swim. Exercise through this relatively mild and classic exercise. At the same time, in the process of exercise, for example, you can find a special medical institution for scientific evaluation. If some actions are uncomfortable once done, stop immediately and don’t do them.

  We encourage middle-aged and elderly people to exercise outdoors properly. During the exercise, they should do it step by step and according to their abilities. If they encounter any discomfort, it is best to consult the relevant doctors and not blindly follow the crowd. (Reporter Yuan Wei Ma Yunfei Chen Jie Xing Zi)

How to play the pan-entertainment social platform in Miyi’s future exploration?

  Socialization is the interaction in society, entertainment is the spice to make life more interesting, and entertainment social products are a kind of products that establish two-way social relations through entertainment interaction.

  Under the combination of different media, a variety of online social experiences have been formed, breaking the relationship blockade period and quickly establishing a relationship circle. At the same time, entertainment and social play are becoming more and more abundant, and the social needs of different groups of people are met through diversified interactions.

  However, as the stock market becomes more and more difficult to do, and the competition on social tracks is getting bigger and bigger, where are the new opportunities? Perhaps, the Z generation users can give us the answer.

  According to relevant statistics, the social activity of Z-generation users accounts for 83.6%, and nearly 70% of Z-generation users in China use online social networking to expand their circle of friends.

  They prefer pan-entertainment, love listening to music, playing games, like to try out various apps, and drive social interaction with interesting and entertaining content.

  As a social product, everyone knows the truth that "the user gets the market". So how do you explore this road? Let’s take the social product Miyi as an example.

  Miyi was launched in 2020. In the early days, it was a simple chat software, supporting text, voice, video and other communication methods. Later, it gradually enriched the entertainment section and added functions such as dynamic square, live broadcast and family.

  Because of the late start, everyone remembers Mo Mo, Exploration and Soul, but no one knows this social software called "Miyi".

  Until later, after innovation and reform, the product gradually added many entertainment elements, attracting a large number of young people to join, and gradually began to become famous, and even once occupied a place in the social list of App Store.

  In January this year, Internet Weekly, a subsidiary of China Academy of Sciences, published the list of "2023 Dating Apps", and Miyi made the list for the first time with her own strength and reputation.

  Judging from the current product development direction of Miyi, its positioning is a comprehensive entertainment interactive social platform focusing on making friends and covering various types such as video, live broadcast and community.

  Video is highly synchronized in real time and highly interactive. Just like real chat and offline meeting, your social signal can get immediate response and feedback.

  Live broadcast is to enhance the entertainment of social scenes, whether it is performing talents, live PK, or live chat and making friends, it pays more attention to the freshness and excitement of "social+entertainment".

  The community square is a place where users post dynamic exchange of interests and share bits and pieces, which can be regarded as a tree hole. In addition to supporting text and pictures, it also supports video carriers, and there is no limit on the duration of video.

  The purpose of the community is to promote user communication. Here, you can share your favorite music, favorite games, favorite books and so on. Connect the community and entertainment to form a larger social entertainment ecosystem and provide users with quality content services.

  From the scene point of view, compared with the LBS matching function of traditional stranger dating software, Miyi maximizes the attributes of pan-entertainment social platform and pays attention to providing users with more interesting and relaxed social ways.

  The unique social ecosystem of interest and entertainment can stimulate users to make use of fragmented time for high-frequency entertainment social in teraction, and quickly establish and expand network social relationships on the platform.

  Of course, as a pan-entertainment social app, in fact, Miyi can also add elements of game interaction in entertainment.

  The game itself is a kind of entertainment with interactive and multi-modal experience, which "acts under certain goals and rules and finally produces feedback".

  The purpose of studying gamification is to understand clearly whether the game, as a carrier, can better help a wider range of users to focus on the product core quickly, so as to obtain emotional satisfaction and maintain this social relationship for a long time.

  We have reason to believe that if the game elements are added, this product will be unique in the social track.

Interview after MWC Exhibition | Whale Technology accelerates overseas layout to help customers release digital productivity

Thousands of miles away, on the other side of the ocean, Internet service applications, from mobile payment, e-commerce to small program platforms, which are very mature in China, are blossoming overseas with the successful mode of digital transformation of China market exported by a batch of outstanding enterprises. Whale technology, which is committed to becoming the world’s leading provider of digital technology and services, is one of them that deserves great attention.

"Whale Technology has been exploring the international market since 2005, and has provided digital technology and services to telecom operators, public service departments and customers in other industries in more than 80 countries and regions around the world." Cao Zhenzhong, chief marketing officer of Whale Technology (International), said in an exclusive interview with C114 after MWC24 Barcelona, "China market has rich technological innovation and practical experience in the digital field, and Whale Technology is actively applying these successful cases and technical experience to overseas market projects. On the one hand, we join hands with overseas operators to accelerate our own digital transformation; On the other hand, on top of the modern digital infrastructure of operators, the digital economy of the market we serve is also entering the fast lane of development, and the whole society is benefiting from it. "

Future first-mover connection

"Future First" is the theme of this year’s MWC24 Barcelona, and the deep integration of 5G and AI has become one of the most concerned topics of this year’s participants. From the commercialization of 5G in 2019 to the announcement that China telecom operators will start the large-scale deployment of 5G-A, the evolution and upgrading of technology has never stopped. An obvious truth is that technology empowers business value, and conversely, the realization of business value will also promote technology to go further. However, in the telecom industry, realizing such a positive cycle is becoming an urgent problem for the whole industry.

When Whale Technology was founded in 2003, the mobile communication market was still in the 2G era, and the demographic dividend made telecom operators enjoy a long-lasting barbaric and extensive growth. At that time, it was even dubbed as "the era of making money while lying down". Nowadays, most telecom operators in the world are facing the embarrassing situation that their revenue growth is slowing down, or even OTT companies are grabbing most of their profits. This is no secret in the industry. Then, as a company that has taken the communication industry as its main development channel since its establishment, how does Whale Technology help operators to meet such challenges?

"Our BSS and OSS suites are powerful tools to support operators to realize 5G realization." Cao Zhenzhong said that the latest telecommunications BSS/OSS suite exhibited by Whale Technology at MWC24 is not only equipped with AI-driven sales, marketing and service platforms, but also can help operators improve customer acquisition efficiency and the life cycle value of existing customers. At the same time, cloud native technology and process automation technology can be used to help enterprises simplify internal workflows and improve operational efficiency.

In addition, in terms of self-intelligent network, telecom operators can use the technology of Whale Technology to build a modern network and operating environment, and improve network scalability, reliability and resource utilization. As for how to monetize 5G, Whale Technology can cooperate with telecom operators, especially overseas operators, to bring innovative technologies and services that have been verified in China market to the market together, and help them gradually shift from 5G B2C to B2B and then to B2B2X and other fields, thus expanding their income sources.

Beyond connection, from paving the way to empowerment, from basic communication connection service provider to digital service provider, this is the core of the answer given by Cao Zhenzhong in an interview.

Last year, at MWC23, GSMA proposed the Open Gateway initiative, hoping to unify and open the network capabilities in the telecommunications network through API, and reproduce the magical effects brought by global voice roaming in that year, thus providing new possibilities for 5G revenue generation. This year, GSMA announced at MWC24 that as many as 47 mobile operator groups (representing 65% of global connections), including the three major operators in China, have signed the Open Gateway plan.

"We believe that the opening of telecom network capacity will bring new revenue opportunities to operators. Especially in the B2B market, operators mainly sell connectivity, cloud resources and resell third-party services. However, in order to enhance the stickiness with partners, operators must open their own capabilities and embed them into third-party services. This can not only increase the profit of B2B business, but also improve the stickiness with partners, and at the same time become a differentiation factor for operators from hyperscalers. If these capabilities are effectively standardized, it can also reduce the integration cost of global partners and promote the development of the entire ecosystem. " Cao Zhenzhong said.

It is also in this context that Whale Technology demonstrated a complete B2B solution at MWC24, covering the B2B support system of operators and TaaS(Telco as a Service). According to reports, TaaS includes a series of solutions, including not only messaging platform as a service (river map) products in the traditional network/communication capability open field, Video Intelligence in the data and AI capability open field, AIGCortex platform (large model platform) and application scenarios, but also operational capability open solutions such as SuperAPP and DMC (digital marketing cloud). Moreover, these solutions have been commercialized and verified in China, Singapore, South America and other markets. At the same time, Whale Technology is also strengthening cooperation with important industry organizations such as GSMA, hoping to actively contribute to ecological construction.

No China, no world.

Huang Yuhong, president of China Mobile Research Institute, recalled MWC2024 Barcelona, and said that besides "no 5G, no AI", there was also "no China, no globe".

In South America, which is separated from Wan Li, as a representative enterprise of China’s technology "going out to sea", Whale Technology helped South American operator Claro to build a Super APP based on small programs and build a local ecology. At the same time, the company held the "Mini Program Super APP Competition" in conjunction with Universidad de La Sabana and Claro in Colombia, aiming at inspiring the younger generation to explore and explore small programs. After receiving the professional training of Whale Science and Technology Instructor, the students of Universidad de La Sabana designed and developed a small program that can solve practical problems in campus life within two weeks. This activity not only allows students to understand and apply knowledge in practice, but also helps local people to cultivate digital talents. It also makes the innovative technology of applet more widely promoted in the American continent, and it is an attempt to integrate science and technology, business and education.

In C114′ s view, the rich ICT experience and industry insight accumulated in the telecommunications field from the 2G to 5G era, coupled with the super blessing of cloud technology and Internet industry experience, has successfully changed from a software service provider to a "digital intelligence service professional company" that understands the telecommunications ICT field, cloud services and Internet genes, which is also the basis for its ability to compete and cooperate with industry giants in overseas markets.

Take the LPC (Local Public Cloud) solution provided by Whale Technology for overseas markets as an example. This solution realizes the efficient operation of major cloud platforms through its self-developed CRE engine. "Our LPC solution enables IDC customers or carrier customers to transform into cloud service operators. They can choose a suitable cloud base scheme according to their own needs and build a cloud infrastructure that meets their own needs. Zain, a Saudi operator, is one of the successful cases. LPC not only meets the requirements of Zain and the Saudi government for data security and data protection, but also achieves sustainable development in business. " Cao Zhenzhong told us that LPC scheme can greatly reduce the threshold for customers to intervene in cloud computing and digital transformation, and provide new infrastructure options for digital transformation of overseas customers.

We have noticed that this scheme has been quoted by Gartner as the sample vendor of the "sovereign cloud". Gartner’s latest forecast also shows that by 2027, 70% of enterprises adopting generative AI will take sustainable development and digital sovereignty as the primary criteria for choosing public cloud generative AI services. In view of this, the LPC scheme is also constantly developing. At this year’s MWC24, Whale Technology launched the Local X series under the background of "digital sovereignty". Local X includes a series of local applications, such as Local Mobile Payment, LocalGPT, Local SuperAPP, Local Security and so on. These digital infrastructures can help a country to establish local, controllable facilities that meet the national regulatory requirements, while Whale Technology has the ability to plan, build and operate such digital infrastructures.

In fact, since 2005, Whale Technology has continuously increased its overseas layout. Up to now, Whale Technology has covered 150+ mainstream telecom operators in more than 80 countries or regions on six continents, serving nearly 1.8 billion end users. In the field of cloud computing and industry digitalization, Whale Technology is the core cloud MSP partner of Alibaba Cloud, and its LPC products have been commercialized in Indonesia, Saudi Arabia, Algeria, South Africa and other countries. Up to now, Whale Technology has set up several R&D centers or branches in the Netherlands, Luxembourg, Colombia, Mexico, Saudi Arabia, Singapore, Thailand, India and other countries.

"A year’s plan lies in spring". After the opening ceremony of MWC24 in Barcelona, Cao Zhenzhong also conveyed to C114 the company’s determination and development goal to continue to deepen overseas markets in the future: with the arrival of the new year, Whale Technology will continue to uphold and practice the "STRATO" strategy of digital transformation 2.0 in the international market. Due to the increasing demand for digital infrastructure, supervision and security in overseas national strategies, LPC-based Local X will become an important development direction. At the same time, the company will gradually move from the telecom operator industry to the digitalization of other industries such as finance and cross-industry digitalization capacity building in order to achieve sustained growth.

You need to know these things in advance to play around the top ten Chinatowns in the world!

Chinatown detective 2


Special feature of 1905 film network The second part of the "Tang Detective" series has met with you in the Spring Festival. If the first action reasoning comedy is a new attempt, then the director Chen Sicheng is even bolder in the second part. He opened a brand-new "detective universe" similar to the Marvel movie universe in his new film. Then, that is to say, the "Tang Detective" series is bound to travel all over the world in Chinatown!


Chinatown is an area where Chinese live in concentrated communities abroad, which is what we call China City. Up to now, except Antarctica, there are many Chinatowns on every continent, totaling nearly 70. Detective chinatown has been to Bangkok and new york.


As a witness to the history of overseas Chinese, Chinatown gives countless wanderers a sense of belonging. Besides Chen Sicheng, there are also many directors who are willing to tell stories related to Chinatown in movies, such as roman polanski’s. But there are not many real shots in Chinatown.

Today, we have carefully selected ten amazing Chinatowns. Let’s go shopping with the movies. I would also like to make a suggestion to director Chen, and "Tang Tan" can go in this order next!


Chinatown, New York, USA


Features: Bearing the ancient history.


New york’s Chinatown is located in Lower Manhattan, the southern tip of new york City, with an excellent geographical position, not far from the city government and only a few feet away from Wall Street. In Detective Chinatown 2, Haoran Liu and Wang Baoqiang parachuted into new york, investigating the case of Wu Zhihao, the grandson of the godfather of Chinatown, who died suddenly. The story started in Chinatown and spread to the whole Manhattan City.

Chinatown in new York

New york’s Chinatown is quite old, which was first formed in 1890. It is centered on Don’t Street and includes Kennedy Street, Baiye Street, Laffille Street and East Broadway Avenue. There is also a Confucius Square on one of the streets. Most of the people who came here were Cantonese and Fujian. In the early days, Americans passed the Chinese Exclusion Act because the Chinese robbed them of their jobs, and it was not until the end of World War II that it was abolished.


The restaurants in Chinatown are always the places that people pay the most attention to. There is an old-fashioned Cantonese dim sum restaurant "Nanhua Tea Room" in Chinatown in new york, which has been visited by many celebrities and its interior decoration is quite retro. In the movie, Yuan Wah and Ceng Jiang appeared in Chinatown, and both the buildings and the signboards were full of Chinese style.

Tell the story of China well. The domestic food documentary "Fragrance" is overseas.

China is a gourmet country. Delicious food with good color, smell and shape, distinctive food schools, unique flavor that makes people linger, etc., have all become the theme of documentary performance.

From China on the Tip of the Tongue, Looking for Shunde, to Taste of Old Guangzhou, Origin of Flavor Chaoshan, and recently, the first season of Flavor World was successfully released to many TV stations around the world, covering many countries and regions in Asia-Pacific and North. Domestic food documentaries not only focused on the food culture and living habits of contemporary China people, but also tried to export China culture overseas, opening a window for the world with documentaries.

Although food culture is natural and international, it is the best international communication theme. However, domestic food documentaries not only present the richness and diversity of China food, but also show some humanistic stories behind the food, and convey profound people’s livelihood and people-oriented important ideas, which has become an important window for the world to understand China.

Tell wonderful food stories

China on the Tip of the Tongue has three seasons. The first season was premiered in 2012, which aroused heated discussion and widespread concern. It was quickly translated into many languages and sold to more than 80 countries and regions, making it one of the most distributed documentaries in China.

Watch China on the Tip of the Tongue, and you will find that it is quite similar in structure to those representative BBC documentaries. BBC’s natural history documentaries mostly add more modular structure and more entertainment elements to the traditional documentary techniques, forming a program style called "documentary entertainment" and being accepted by the public.

Similarly, China on the Tip of the Tongue also uses cross-editing, focusing on food, telling stories between people and food, between people, between people and hometown and even between home and country, enriching the expression space and creation space of food documentaries and deepening the ideological connotation of food festivals. In addition, it also contains some humanistic thinking, telling the geography, ceremony and ethics behind the food with concise narration, so that the audience can feel the long history of Chinese food culture.

Since then, a large number of food documentaries have followed this creative method, telling a lot of life or life stories around food. Some even tell transnational stories and bring more international elements into documentaries. Food or ingredients are just clues that run through an episode of documentary.

For example, the series of documentaries "Origin of Flavor" takes food as the window, explores the rich products in China, praises farming and labor, and shows people’s life concepts in different regions with delicious food as the medium. Flavor Origin series documentaries, Flavor Origin Chaoshan and Flavor Origin Yunnan, are the first documentary works produced by China team that Netflix took the initiative to purchase copyright and promoted globally.

Flavor world

Flavor Room examines the uniqueness of China cuisine from a global perspective, explores the evolution of China cuisine in the process of historical evolution, and deeply discusses the relationship between people and food in China. This global perspective has made a diversified "food exploration documentary". For example, the episode "Chicken Style Theory" in the second season of "Flavor World" covers more than a dozen chicken dishes, such as chicken stewed with mushrooms and chicken jiaozi in Heilongjiang, roast chicken and marathon chicken in Africa, ginseng soup and fried chicken in Korea, shredded chicken with ginseng soup and roast chicken in Suzhou, Anhui.

Chen Xiaoqing, director of Flavor World, once said, "Food is the best goodwill ambassador." Food documentaries not only introduce China’s diet with spectacular images and dramatic stories, but also explore the world outlook, values and choices of lifestyle and interpersonal relationships belonging to China culture by means of diet in a way that can be understood by contemporary and even world audiences.

Show the real life of ordinary China people.

In addition to the colorful food itself, the daily life of ordinary people has also become the theme of documentary performance. Ordinary people coming to the front desk of the documentary not only vividly show how China people extend their historical traditions to their present life, but also help other cultural groups to overcome obstacles and barriers and understand the real China people and China culture in the context of contemporary life.

"A String of Life" focuses on barbecue food, showing the scene that ordinary people in China enjoy barbecue. In order to improve the daily scene effect of the picture, the film aims at the noisy streets, smoky kebabs, people with big mouths and scattered bamboo sticks. These pictures highlight a scene in the life of ordinary people in China, which is very real.

"Breakfast China" focuses on breakfast in three meals a day. By showing various special breakfasts, it tells the daily life stories of shopkeepers and shows their mental state. Although the program is short, only a few minutes, but from a few words and simple pictures, we can observe the living conditions of ordinary China people in the fireworks. Together with documentaries about China’s great achievements, rapid economic and social development and changes, these short stories about ordinary people’s daily diet and life constitute a true three-dimensional and comprehensive China.

Create a gourmet "video spectacle"

The unexpected exquisite pictures, especially the "image spectacle" with strong visual impact, are the important reasons why many China food documentaries are welcomed by overseas audiences. China has a vast territory and abundant resources, and its rich ingredients have created a variety of eating habits and culture, which not only provides rich materials for documentary creation, but also provides a huge creative space for creating a unique "video spectacle" of food.

The first season of China on the Bite of the Tongue was taken from different provinces in China. The unique geographical and natural environment, the unique ingredients and their cooking methods, and the mature process of food production are transformed into amazing spectacle images under high-definition cameras and a large number of microscopic lenses.

The diversity of "Between Mountains and Seas" in "Flavor World" presents the south bank of the snow-capped Ulungu River in Xinjiang, the simple and beautiful ancient town Nanping, the endless wheat fields on the Heluo Plain, the plateau landforms in Gansu and the dense mountains in the southwest, bringing the audience into the vast mountains and rivers of China and the magnificent artistic conception.

In addition to constantly exploring the food content, these documentaries also draw lessons from the production mode of "high concept" and pursue the audio-visual level of "film texture". Close-ups with shallow depth of field and aerial photography with special perspectives reflect the pursuit of spectacle effect in Internet documentaries. These comparable film quality and carefully selected shooting themes together constitute a spectacular viewing effect, which has become an important driving force for documentaries to improve quality and market performance in recent years.
