Where did the Japanese ancestors come from? What about North Korea and South Korea?

North Korea and South Korea are mainly descendants of Yan and Zhao in the Warring States period, which can be said to be descendants of the Chinese people. Japanese, generally considered as ancient Malays who sailed internationally, are also descendants of Zhao Yan, Zhoukoudian Beijingers and Dayu tribe. Japanese people are the most inclined to China culture in the world, and are ashamed to admit that they are descendants of southern barbarians.
