Yangshe clan

According to surname records, the Chinese surname Yangshe (羊舌) originated in the state of Jin. Marquis Jing of Jin's son, Boqiao (伯僑) has a grandson named Tu (突). During the time of Marquis Xian of Jin, Tu was given a land called Yangshe, modern Hongdong County and Qin County, Shanxi, by Marquis Xian of Jin. Therefore, Tu's clan name became Yangshe and this is where the surname Yangshe started.
