The origin and history of Minnan dialect: Before the Han Dynasty, Minnan dialect was the indigenous of Guyue nationality. It was the first great disaster of the Han nationality in the Central Plains-the "Yongjia Rebellion" in the second year of Yongjia in the Jin Dynasty (308). The gentry of the Central Plains crossed south, and eight surnames, Lin, Chen, Huang, Zheng, Zhan, Qiu, He and Hu, took the lead in Fujian, bringing the Yellow River to the Central Plains. Later, Hou Jing's rebellion, Sui and Tang Chinese when he entered Fujian in 1969, and Wang Gushi's entry into Fujian to establish Fujian infiltrated and merged together to form the present Minnan dialect. The origin of the above-mentioned entry into Fujian is recorded in detail in the genealogy of Fujian surnames such as Chen, Lin and Huang. There are many ancient Chinese in Minnan dialect, so it is called "the living fossil of language" by academic circles. Minnan language has always been valued by linguists at home and abroad. This is of great significance to the phonetic construction of ancient Chinese, the interpretation of ancient books and the study of Chinese history.
