History Why are some traditional cultures originating from ancient China carried forward in South Korea and Japan?

This can be said for three days and three nights, but in summary, it is the brain supplement of the ruling party. Look at the kimono, you know, it used to be called Hanfu, which was the dress of ancient court ladies. The Japanese said "hi", remember? Qin Khan and the affirmative sentence of replying to his superiors used to be called "ha", so the Japanese learned it here. Tatami knows. China's house was paved before the Three Kingdoms, and it is learned. Korean people know the wedding ceremony. They learn Taekwondo and Karate from China. It's too far, doesn't the mountain city know? See what Tangdao looks like. These things have been carried forward since they were exported. It's all industrialized now. I don't know how much tax revenue it brings and how much employment it creates every year. Those who are in power above me don't care about these things. They only spend money to buy US Treasury bonds, and the result is blind.
