What are the hazards of dialect disappearance?

The disappearance of dialects will lead to the decline of cultural inclusiveness in China. I have some foreign friends studying in China. If they have an Asian face, whether they are Koreans, Vietnamese or Thai, they can speak a certain level of Mandarin. Often, they are not regarded as foreigners in China, but as Hong Kong people whose Mandarin is not good enough or people from southern provinces. This experience of being mistaken for China people has greatly enhanced their affection for China and made their life in China more comfortable.

Compared with Japan and South Korea, where ethnic homogeneity is very high, the concept of "Huaxia" is actually based on culture rather than race since ancient times. Even under the influence of western nationalism, due to the differences in people's looks and languages, the definition of "natives" in Chinese mainland today is often much looser than that of our neighbors. When friends from Taiwan Province Province come to the mainland, it is very easy to pretend to be people from a southern province in front of most ordinary people. Even though there are obvious differences in accent and speech, on the other hand, mainlanders are often caught going to Taiwan Province Province, which is the diversity difference. This diversity is the basis of "four families coming to Korea" in ancient China, represented by the Tang Dynasty, and it is also a necessary condition for China to expand its international influence in the future. Don't you see how Japan, which lacks diversity, was defeated in international competition and gradually retreated to "island culture"? If one day dialects disappear and people all over the country speak standard Mandarin, the concept of "China" will naturally narrow, and China's tolerance for different cultures will inevitably decline, which will not only affect its attraction to foreigners, but also make its national innovation ability not optimistic.
