60% of Fujian ancestors came from Gushi, Henan, and Minnan dialect also came from Henan. Is there any basis? The Chinese nation has a very long historical process, so there have been many large-scale migrations. Therefore, in ancient times, the population distribution between north and south was completely different from now. For example, during the Northern and Southern Dynasties, the population in the north was about eight times that in the south, but later, with the change of dynasties and the migration of the capital, the center of the country also changed, so the population flow also occurred. Fujian, as a province with a small population, can be regarded as a classic case of change. Fujian ushered in the first large-scale population change in the Western Jin Dynasty. Before that, that is, during the Qin and Han Dynasties, the population of Fujian was very sparse. At that time, local residents in Fujian were called Fujian people. At the end of the Western Jin Dynasty, an event called Five Chaos happened, which officially caused a large number of Central Plains people to move south from the north of the Yangtze River. Therefore, Fujian has also received a large number of Central Plains * * *, of which Henan people account for a very large proportion, which is the so-called "eight surnames entering Fujian". According to Records of Nine Kingdoms, these eight surnames are Huang Lin, Zhan Qiu and Hu. The second large-scale population change in Fujian took place during the Tang Gaozong period in the Tang Dynasty. The Central Plains people who entered Fujian this time are mainly from Henan. It is precisely because of this population migration that the largest surname in Fujian is Chen, and Chen has always been the first surname in Fujian. In 669 AD, there were frequent rebellions in southern Fujian, and Tang Gaozong sent Zheng Chen, the leader of Lingnan March, to quell the rebellion in southern Fujian. Since then, Zheng Chen and his subordinate soldiers have been stationed in southern Fujian. Later, Zheng Chen's son Chen Yuanguang took over his father's position and continued to stabilize southern Fujian. Later, Chen spread around in the local area. Today, there are still many people surnamed Chen in Fujian who are regarded as "kings". At the beginning, most of the soldiers who followed Zheng Chen and Chen Yuanguang to Minnan were from Henan. In the process of sending troops, 58 surnames were transferred to Fujian. For example, the current surname of Lu in Fujian comes from Lu Rujin, a general who first followed. In the late Tang Dynasty, Wang Xu organized a large number of troops to carry out large-scale looting, which offended many people and forced him to turn to Fujian. Later, because the control was too cruel, he was killed by the three brothers. Later, Wang Chao succeeded Wang Xu Secretariat. They gradually expanded their power and territory and established Fujian.
