1. Some Koreans despise not only Yanbian people, but also China people. In their eyes, China is very backward. My friend was asked if there were any bananas in Korea. Another time, a Korean tourist went to my friend's place for a massage. My friend was so embarrassed that he even gave me a tip for my friend to eat meat. This kind of thing is searched a lot online. South Korea falsified history, robbed China's intangible cultural heritage of registering patents at the United Nations, and belittled others to enhance its sense of national superiority and honor.
Most of Yanbian's trips to Korea are for Koreans. What some Yanbian people did in Korea also affected their reputation.
