The house of Yangshe 羊舌 was a noble family in the state of Jin 晉 during the Spring and Autumn period 春秋 (770-5th cent. BCE). They were descendants of Marquis Jing of Jin 晉靖侯 (r. 859-841) and therefore bore the family name Ji 姬. Yangshe was actually the name of their fief located in the southern parts of the modern province of Shanxi but was also used as a kinsname (shi 氏). There were four branches of the family Yangshe, all of which were influential noblemen in Jin. The family possessed three fiefs, namely the towns of Tongdi 銅鞮 (near modern Qinxian 沁縣, Shanxi), Yangshi 楊氏 (near modern Hongdong 洪洞, Shanxi), and Pingyang 平陽 (near modern Linfen 臨汾, Shanxi).
Duke Wu of Jin 晉武公 (r. 717-677) had a son called Bo Qiao 伯僑, who was enfeoffed with Yangshe. His great-grandson was Yangshe Zhi 羊舌職 who had five sons: Yangshe Chi 羊舌赤, grand master (dafu 大夫) of Tongti; Yangshe Xi 羊舌肸, grand master of Yangshi 楊氏; Yangshe Fu 羊舌鮒; Yangshe Hu 羊舌虎; and the youngest son Yangshe Jisu 羊舌季夙. Yangshe Xi had a son called Yangshe Bo Shi 羊舌伯石, courtesy name Shiwo 食我, also called Yangshi 揚石. He sided with Qi Ying 祁盈, who was unluckily involved in a rebellion against the duke of Jin.
The houses of Qi 祁 and Yangshe were therefore extinguished, barring a few members of the family who hid to the wilderness of Mt. Huashan 華山 and later settled down in Huayin 華陰. Their descendants adopted the family names Yang 羊 and Yang 揚 (or 楊).
