Ouyang appeared in the Spring and Autumn Period, while Qu only appeared in the Han Dynasty. Therefore, people in the clan of the district humbly call it Xiaoqu and "Ouyang" as Big Europe. Some Yang surnames originated from Ouyang surnames, but it was after the end of the Northern Song Dynasty that Ouyang surnames were divided into Yang surnames. Now, the family of Yang surnames whose ancestors are Ouyang mainly lives in the middle and lower reaches of the Yangtze River. The surname Ouyang (茟莍莍) originated from the same family as the European surnames, and established the state of Ou Yue in (333-BC), and Ouyang Zaixun became the king in (333-before).

Destroyed by the State of Chu, the boundlessness of the second hoof was sealed in the south of Ouyu Mountain in Wucheng, with Shannan as the sun, so it was called Ouyang Tinghou, a boundlessness descendant of ordinary people. Therefore, three surnames, Ou, Ouyang and Ou Hou, were formed with the name of fief mountain and knighthood. First ancestor: boundless. Ouyang is a descendant of Gou Jian, the famous king of Yue in the Spring and Autumn Period.

When it was spread to the King of Yue, it was destroyed by the State of Chu, and his son's hoof was changed to Ouyang Tinghou, the southern part of Wucheng Ouyu Mountain, and his descendants took Ouyang as their surname. According to "Hundreds of Surnames in Counties", Ouyang's noble family lived in Bohai County, which is now Cangxian County, Hebei Province.
