First of all, "Little China" was not put forward by the Chinese, but invented by the Koreans, Japanese and Vietnamese. They believe that all countries infected by Chinese civilization to some extent can be called "Little China", which is the product of a specific historical period.
Countries in East Asia have gradually become international standards for learning from the ancient and advanced Chinese culture. Most countries have absorbed Chinese language and culture and formed a common Confucian civilization circle, but it has never been a unique civilization in China. The Japanese, Vietnamese and Koreans have made many contributions to Chinese civilization.
In the 13th century, the Mongols ruled China and established the Yuan Dynasty, which led to the collapse of the orthodox image of ancient China.
The Japanese and Vietnamese gained greater national pride by defeating the Mongols. They believed that the pure Chinese culture was destroyed by the Mongols. They actively protected the tradition of Chinese culture. Since then, they called themselves "Little China". Many people in Taiwan today still believe that Chinese orthodoxy is in Taiwan.
Vietnamese used the idea of "Little China" to establish their own tributary system in Southeast Asia and annexed zhanba. The Japanese used the concept of "Little China" to explain their invasion of the Qing Dynasty and the Korean Peninsula.
Chinese culture is not so fragile. The rulers of ethnic minorities such as Mongols can't destroy it because China is too big, has too many people, has too long history and has too rich accumulation.
Some people support the idea and statement of "small China", believing that it can increase national pride. Some people oppose the idea of "small China", believing that it will damage national pride. This complex idea also reflects the ambivalence of China's neighbors. They want to get rid of China's influence, but they can't give up Chinese culture.
But these are customs and thoughts left over from history, which are no longer applicable to modern society.
Because people believe that the concept of "small nationalism" has spread to the west, it has become a more important concept of "small nationalism".
Vietnam and South Korea have completed de sinicization, and Japan has also absorbed a large number of western culture. Even the Chinese have tried their best to learn everything from the west after the new culture movement, and even almost completed the overall Westernization. In recent years, they are trying to revive the traditional culture and shape the uniqueness of Chinese culture.
China doesn't like such a name, and so does Vietnam, largely because it is "politically correct".
Vietnam also has a long history. The history of "Vietnamese" tribes related to modern Vietnamese can be traced back to China's Qin Dynasty. Vietnamese do not like to be called "Little China", although it is affected politically and culturally, and may be the country with the highest degree of Sinicization.
The Chinese do not regard Vietnam as a trumpet China, but as an ancient civilization growing independently. It has a long history. Although it has been occupied for a long time, it has been forced to become a tributary of a powerful civilization.
So please don't say that Vietnam is a small China. Neither Vietnamese nor Chinese will appreciate this kind of condescending. It's like saying that Canada is a small United States, New Zealand is a small Australia, Ireland is a small Britain and Nepal is a small India. This statement is like a joke and ridicule.
Over the past 2000 years, Vietnamese people have shared or absorbed many contents of Chinese culture, including characters, names, customs, lunar calendar, architecture, religion, Confucius or family values. Chinese who visit Vietnam and their homes will be surprised to find how similar they are.
Both are close culturally and economically. If the two countries had more friendly exchanges in history, they might form an alliance today.
China and Vietnam are eternal neighbors, connected by a long land border; There are bridges, highways and even high-speed railways. There are three main crossing points where people often come and go to each other.
Vietnamese are similar to most southerners in China and other ethnic minorities, and sometimes difficult to distinguish. For a long time, various "Vietnamese" tribes and Vietnamese have been integrated with the blood of the Chinese people. There are some Thai people in Vietnam, with 51 nationalities, but the main Jin people (86%) do have a certain proportion of Chinese descent.
China is one belt, one road member of the Asia Investment Bank and the China ASEAN partnership, and has free trade agreements with China. They are doing well as economic partners and cross border trade is booming.
Both countries feel that it is good to develop mutually beneficial relations and there is no need for some inexplicable nicknames.
Of course, most Vietnamese and Chinese will answer "no" to this question, but I don't think this is what the person asking this question wants to know. The wording of this question is a little disrespectful to the Vietnamese. It should be described as: in practice, why is Vietnam so similar to China in culture?
Vietnamese people usually think of Chinese as "th â m hi â m", which is a word difficult to describe in English. It includes the expressions of witty, cunning, cunning, profound and complex people, visionary people and cunning people. It has both positive and negative meanings. When Vietnamese say that Chinese people are th â m hi ể m, their feelings are often intertwined with fear and admiration.
越南人通常认为中国人是“thâm hiểm”， 这是一个很难用英语描述的词。它包括机智、狡猾、狡猾、思想深刻复杂的人、有远见的人、狡猾的人等表达，既有正面的含义，也有负面的意思，当越南人说中国人thâm hiểm，那他们的感情常常是恐惧和钦佩交织在一起。
Apart from politics, both countries abide by Confucianism and filial piety, including ancestor worship, Chinese cooking, Buddhism, pagodas, architecture, appearance (especially North Vietnamese, and most South Vietnamese immigrants from the north, who look like Chinese in the South or some even in the North), national system, Chinese characters (until abolished a hundred years ago), Chinese literature, novels The current Chinese TV series, the Chinese new year, the lunar calendar, the Mid Autumn Festival and some other important Chinese festivals, and even people's behavior on some social occasions, and the current trade partnership between the two countries are more and more closely linked.
Of course, if they deeply study the structure of the two societies, they will find some differences, but even in China or Vietnam itself, cultural differences do exist at the regional level.
Of course, some typical Vietnamese cultures are unique and can't be found in China, but I won't introduce them in detail here, but the main contents listed above must be the common ground between the two countries.
In my humble opinion, no other country in the world has so much in common with China as Vietnam, even South Korea, Japan or Mongolia.
