1. In the early years of the Western Zhou Dynasty, his son was named Tang, and the son of the later Tang Dynasty was renamed Jin. When the State of Jin spread to the 11th Sun Jinwu, she called her second son Bo Yang and Yang Hou, the ancestors of Yang. The grandson of overseas Chinese in Houbo suddenly ate sheep's tongue, so it is also called sheep's tongue. In the 12th year of Jin Qinggong (the first 5 14), the family was destroyed by Jin, and later Yang Dao fled to Huashan, where he lived in Huayin, Hongnong, and took Yang, the ancestor's fief, as his family name. His descendants flourished and gradually developed into a "Yang Authentic Family".
2. In Western Weekend, Zhou Xuanwang Ji Jing named his son Yang Guo (now Hongtong County, Shaanxi Province) Yang Hou. During the Spring and Autumn Period, Yang was destroyed by the State of Jin, and his descendants took Yang as their surname.
Migration and communication
Yang's birthplace is in today's Shanxi Province. In the Spring and Autumn Period, Yang was destroyed by gold, and the surname Yang developed and spread westward. He first moved to Shaanxi, then moved to Huoxian county in the middle reaches of Fenshui River in Shanxi, and then spread to Henan.
During the Spring and Autumn Period and the Warring States Period, some Yang people moved to Jianghan area (now Qianjiang area in Hubei Province). Later, due to the growing influence of Chu, they moved to Jiangxi in the southeast. At the same time, Yang people moved from Shanxi to Jiangsu and Anhui, scattered in the middle and lower reaches of the Yangtze River.
During the Qin and Han Dynasties, Yang moved to Hanoi and Fengyi (now Dali, Shaanxi), which were widely distributed in the north of China. Yang entered Sichuan at this time, mostly from Hubei and Shaanxi.
