As for Koreans, my long-term contact with Koreans gives me the feeling that the biggest shortcoming of Koreans is that they love to brag and are not modest. If China people are too modest, then Koreans are too arrogant. Sometimes, in order to show their advantages, they will say many untrue things, such as that they have only one car at home, and they will say that they have two cars, but they are just employees, and what kind of titles they have.
However, apart from this aspect, I haven't found any other common shortcomings of Koreans for the time being.
As for South Korea's views on China, in fact, many people in China still don't know. Nowadays, South Koreans are basically impressed with China, except for some elderly people. Most young people not only don't look down on China, but many people want to start a business in China very much. They know that China is developing rapidly now, which is like a piece of fat meat for them, because it is very difficult for South Korea, as a capitalist country, to start a business, unlike China, where many things are still immature and there is a lot of room for development. Therefore, in the answer, 118376824 on the first floor said that Koreans think that we are still very ancient, because the idea of 118376824 is still in the past.
In addition, the China movies that South Korean TV stations are playing now are not those things that China is lagging behind. Our family watches Korean satellite TV, some of China's latest TV dramas are broadcast, and some variety shows that they come to China are often broadcast. They are basically big cities or scenic spots, and the places I have seen are Shanghai, Xiamen and Zhangjiajie. Therefore, Koreans' understanding of China today is still relatively modern.
In addition, Koreans are impolite only to those who don't like them, and they are polite in other cases.
In short, the lives and thoughts of different ethnic groups will be different, and it is difficult to finish at once. I also think that this topic is not worth much discussion. Every nation has its own advantages and disadvantages, and there are different good people and bad people. So I think a really wise person can't simply judge a country and a nation according to some news and news he has seen on the Internet. If you want to really understand, go to that country and live for a period of time, and what you see for yourself is true.
