Why can the emperors of Korea and Japan be handed down for dozens of generations?

North Korea should be because it is our vassal state, and the monarch should be pursued by us, because all dynasties have been under our jurisdiction, so there can be no chaos; Japan is more exciting. The royal family of the Chrysanthemum Dynasty keeps saying that they are descendants of the gods (the supreme god of Japan), but they are actually mascots. Real power is always in the hands of famous figures (such as Toyotomi Hideyoshi and Nobunobu Oda), and then in the hands of shogunate generals. During this period, the emperor was more of a nominal leader and a spiritual symbol. No matter who is in power, he will not be willing to bear the stigma of regicide. After all, what he said is worthless, and no one cares about him at all. It was not until the Meiji Restoration in modern Japan overthrew the rule of the last shogunate (Tokugawa shogunate) that the real power returned to the emperor, but soon a world war broke out. Japan was launched as a defeated country to declare defeat. MacArthur, an old American, entered Japan and the emperor became a puppet. Therefore, a mascot without any real power, but occupying a position of honor and justice, will be troubled by irrational people.

In China, since Zhang Zhongjing ousted a hundred schools of thought, the concept of loyalty to the monarch and patriotism, such as the relationship between heaven and earth, has been deeply rooted in the hearts of the people. The emperor claimed to be the son of heaven and toured the country on behalf of heaven, so their country was generally stable. In Europe, a sparsely populated place, the real power is in the hands of those big noble, and sometimes even dozens or hundreds of people can successfully stage a coup. For example, in the famous Trojan War, several people hiding in Trojan Horse could win by cooperating with the outside world. This is a joke in our country, isn't it a village fight? Just like the Battle of Feishui in China, Fu Jian in the former Qin Dynasty assembled 800,000 troops, claiming that "throwing a whip at the river was enough to stop the flow", and the scale of this war was simply beyond the reach of the West. So, the history of the west will be like what you said.
