Brief introduction of yayoi

China's Qin and Han dynasties (22 1-220 BC) are equivalent to the yayoi period (300-300 BC) when Japanese islands used stones at the same time. The radiation and spread of China culture to Japan during the Qin and Han Dynasties greatly shortened the process of Japanese archipelago's escaping from ignorance and entering civilized society. During the Qin and Han Dynasties, the spread of China culture to Japan was mainly accomplished by China immigrants. In fact, China's immigration to Japan began in Shang Dynasty, Spring and Autumn Period and Warring States Period before Qin Dynasty. At that time, feudal lords fought for hegemony and wars were frequent. Many people from northern China, such as Qi, Lu, Yan and Zhao Zhimin, fled to North Korea, and some indirectly or directly fled to Japan.

During the Qin and Han Dynasties, China's immigration to Japan increased. "Since Chen Sheng, the world has rebelled against Qin, and Yan, Qi and Zhao Min have taken refuge in North Korea for tens of thousands of people". Among them, Fu Su Zong and Hu Hai Zong of Qin Shihuang both fled to Japan. In the Han Dynasty, after Emperor Wu of the Han Dynasty established four counties in North Korea in BC 109 to directly rule the north of Korea, a large number of Han people went to the four counties in North Korea from the headquarters of China to work and do business, and their descendants stayed there. But in 3 13 AD, after China's ruling institutions in Le Lang County and Daifang County were destroyed, the Han people there had to leave there, some people returned to their motherland, and some people crossed the sea south. For China and North Korea, it is an immigration problem. According to the Japanese history book "The History of Japan", at the end of the Eastern Han Dynasty, China immigrated from the Korean Peninsula to the Japanese archipelago.
