Why do Koreans apply for world heritage with our culture? Thank god, help me.

Many people advocate that we should give the strongest response to South Korea's encroachment on the cultural heritage belonging to Chinese civilization. In my opinion, the most powerful way is to declare the intangible cultural heritage by combining the themes of Tai Chi, Yin Yang and Eight Diagrams, which can directly show that even the current Korean flag is the cultural heritage of Chinese civilization. In fact, South Korea or the Korean nation as a whole is a branch of the Chinese nation, which should be highlighted in all kinds of books and activities in the future. As far as intangible cultural heritage is concerned, Chinese civilization is the main body, while Korean civilization is sub-civilization and subsidiary. Even if it is a heritage, South Korea is dominated by China, but it cannot be said that it is monopolized by South Korea. In fact, we don't have to worry about the application for the Dragon Boat Festival. Just because Korea applied doesn't mean we can't apply any more. As long as enough materials are prepared, it is completely possible to declare the Korean Dragon Boat Festival and the Japanese Dragon Boat Festival under the traditional Oriental Dragon Boat Festival, which further shows that both Korea and Japan have been influenced by Chinese civilization in history and culture. It's a shame that Koreans are thieves. A frog in the well is arrogant. It can't be a climate. Korea has no culture of its own. Their ancestors believed in Confucianism, but now they have forgotten their ancestors. How hateful! There is no need to be as knowledgeable as Wang and others.
