Classical theory. According to Tongzhi Genealogy, during the Spring and Autumn Period, Xu Chen, a doctor of the State of Jin (Xu Chen did not say where his surname came from), his descendants took his father's word as their surname, and his surname was passed down from generation to generation. It is generally believed that Xu was Xu Chen, a doctor in Jin Dynasty. According to Zuo Zhuan, Xu Chen, the ancestor of the State of Jin (Zhong Er) in the Spring and Autumn Period (770-256 BC), lived in exile and later made great achievements. Later, I went to Ji to preach, and when I saw Ji lacked tools for weeding, my wife gave it to him. He treated him like a distinguished guest, but it was for the sake of Wen Gong. Meng Mahua, the ancestor of the state of Jin, defeated the Chu army in the battle of Chengpu. Officials worship Sikong, and fiefs (fiefs) are called "Nine", also known as "Ji Jiu", and some descendants take "Yi" as their surname and call it "Nine" or "Ji Jiu". His son, grandson, great-grandson and great-grandson are all "Qinghe doctors". After the death of Chen Xu, that is, four years after the death of King Zhou Qing, Qin Jin went to war with these two countries. Our son wore Zhao, which betrayed the military intelligence. Zhao Dun, the head coach, stripped off the official armor and went to defend the country one by one to use the armor-Tsui Hark. During the Jin Dynasty, Ke's son was from the Qing Dynasty, and he had deep grievances with Luan Shu and Bank of China. Later, Luan Shu and China Bank were favored by Gong Li, and Xu Tong was killed. Later generations changed "Xu" to "Tong" in the name of his grandfather, calling it Tong's (Tongzhi-clan abbreviation). Shanxi and Shaanxi are our roots. ..... From the Southern and Northern Dynasties to the Song and Ming Dynasties, clans expanded to Gansu, Shandong, Hebei, Jiangxi, Jiangsu, Hunan, Anhui, Henan, Northeast China, Sichuan and other places. The Baijia surname named the county where Xu was located as "Langya County": in the Spring and Autumn Period (770-256 BC), it meant "Qi", which is now Langya County in Jiaonan City, Shandong Province. During the Northern and Southern Dynasties (420-479), residents of the Central Plains moved south, and Baixia (now north of Nanjing and south of the shogunate) was a "Hakka", also known as Langya County. "Hundred Family Names" was compiled in the Song Dynasty, indicating that Xu became a noble family in Langya County (possibly Shandong or Nanjing).
