What are the things that South Korea is sorry for China about?

I didn’t even say I was sorry to the Chinese people. In fact, it's not their fault. It’s just that Koreans have a strong sense of national consciousness and attach great importance to cultural assets.

They registered the Dragon Boat Festival as their national traditional festival, but as we all know, the Dragon Boat Festival is for us to commemorate Comrade Qu Yuan.

Also, some Korean people say that Confucius is Korean and Chinese was created by Korea, because many Korean characters are the same as Chinese.

But this is not entirely South Korea's fault. The Chinese did not think of striving for these things. They only felt dissatisfied and complained when others valued these things.

Also, groups of Kazakhs and Koreans are now bringing strong Korean culture to China, such as Korean trendy clothes, accessories, food, movies, celebrities, etc. Especially those born in the 1980s and 1990s, people have forgotten China’s traditional folk culture.

China is not substantively committed to protecting and promoting its own cultural heritage, so I think it is a bit extreme to say that Koreans are sorry for the Chinese.
