Part of the reason why Koreans like to tamper with our inventions is that there are many similarities between Korean culture and 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 on the Korean table, but in China, it is not a 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 making method of Korean rice cakes is not exactly the same as that of China rice cakes, and each place has its own characteristics.
Second, some Koreans don't understand the cultural background of their own country.
Koreans don't fully understand the cultural background of their own country. In this case, we can't maliciously say that other countries have robbed their culture. We should make a judgment after understanding history.
Historically, the development of South Korea is not as long as that of China. Just because China doesn't care about these little things doesn't mean that what South Korea said is right. Our country has always maintained its own attitude and does not 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.
Because of this, I think it is possible that only some Koreans make a fuss and want to use this exposure to attract traffic.
Because in fact, many times we can see that Koreans are too narrow-minded about the cultures of the two countries and do not know how to understand the historical details in depth. For example, a Korean blogger used to send videos in China to make money. She said in a comment that a culture was invented and created by their country. Later, the people of China opposed it. Although the blogger later apologized, he didn't see his sincere attitude. Finally, the blogger was exiled by the company, indicating that the blogger has no market in China.
