When did Japan split from China?

Japan is not independent from China, but before 2000, no one in the Japanese archipelago sent Xu Fu to lead 3,000 boys and 3,000 girls from Shandong to collect elixirs in the Japanese archipelago. Later, Emperor Wu of the Han Dynasty immigrated thousands of residents from Shandong Peninsula to live in the Japanese archipelago, and then lived in Shandong in the Tang Dynasty. In order to avoid the Anshi Rebellion, a large number of Shandong people immigrated to the Japanese archipelago to survive, and then a few immigrants from Southeast Asia and Zhejiang and Fujian appeared in the Japanese archipelago, which combined with each other to become the Yamato people in today's Japanese archipelago. Most Japanese people are descendants of people in China and even Shandong Province, so Japan has been harmonious and different since ancient times. People in China and even the whole Shandong Peninsula and Southeast Asian countries are relatives. Unfortunately, they forget their ancestors too much. They seek roots everywhere, invade, fight, kill, rape, rape and rape people in China and Southeast Asia. Therefore, it is better to be an animal than to be unfilial.
