1. There are similarities between Korean culture and China culture.
Part of the reason why Koreans like to tamper with our inventions is that Korean culture has many similarities with China culture. These similarities make Koreans think that these cultures belong to South Korea.
Take the rice cake as an example, because it is a common food in Korean dining tables, but in China, it is not a very common food in our daily life, but we always have rice cakes. I think it is not surprising that the two countries have the same thing, because from the previous history, there may be cultural exchanges. Moreover, the Korean rice cake is not exactly the same as the China rice cake in terms of production methods, and each place has its own characteristics.
second, some Koreans don't understand their own cultural background.
Koreans don't fully understand the cultural background of their own country. In this case, we can't maliciously say that other countries robbed their culture. We should judge after we know the history.
According to history, the development of South Korea is not as long as that of China. China just doesn't care about these little things, and it doesn't mean that what South Korea said is correct. Our country has always maintained the attitude of being ourselves, and we don't need to pay attention to the tampering of these cultures by other countries. We have always maintained a tolerant heart.
Third, some Koreans like to spread rumors and cause trouble.
For this reason, I think it's also possible that only a part of Koreans spread rumors and want to use this exposure to attract traffic.
Because in fact, we can see that many times, Koreans are too narrow-minded about the cultures of the two countries and don't know how to deeply understand the historical details. For example, a Korean blogger used to send videos in China to make money. She said under a comment that there is a culture that was invented and created by their country. Later, the Chinese people objected. Although the blogger later apologized, he didn't see his sincere attitude. In the end, the blogger was exiled by the company, which means that the blogger has no market in China.
