This was done primarily to differentiate it from the kimchi found in Sichuan cuisine.

Strictly speaking, many parts of Korean culture are derived from Confucianism, which originated in China, so many parts of Korean culture are Chinese things, such as the Korean Dragon Boat Festival and the Spring Festival, which are Chinese festivals. Many of the names of places and items in Korean culture are also named after Chinese culture. Currently, Korea is an independent country, and we have gone to great lengths to further delineate ourselves from certain items in Korean culture.

I. What's the deal with this?

This is a story about Korean kimchi, which was previously known by its Chinese translation, kimchi. Many people often confuse Korean kimchi with Sichuan kimchi, thinking that they are the same ingredient. However, if you look at it in a strict sense, Korean kimchi tastes completely different from Sichuan kimchi, and the practices are also different. It is for this reason that we now officially define the Chinese name for Korean kimchi as Sinchi.

Two, this is done to avoid confusion.

As I mentioned above, Korean kimchi and Szechuan kimchi are very similar and have the exact same name. In order to avoid confusion between the two types of kimchi, it is now precisely the Korean kimchi that is defined as Sinchi, and the name of the Sichuan kimchi remains unchanged from its original name. Korea's many things are originated from China, and I don't think there is a need to argue with Korea.

Three, Korea often applies heritage to so-called festivals and objects.

I remember when I was a student, South Korea applied for intangible cultural heritage for the Dragon Boat Festival, which made me feel particularly angry. Later on, South Korea applied for intangible cultural heritage for many items and festivals one after another, and many people changed from being angry at the beginning to being speechless later on. Anyway, the Koreans are helping and inheriting our Confucian culture, and many people don't want to compete with Korea now anyway, as exemplified by the Korean Sinchi and the Sichuan kimchi.

In summary, the above is my answer to this question, I hope this answer can help you.
