 The origin of the Pei clan is disputed by scholars of Chinese history.Lin Bao, a Confucian scholar of rites, argues that the Pei family descended from Feizi, the founder of the Qin state, the forerunner of the Qin dynasty.On the other hand, some epitaphs of the members of Pei family trace their origins to Pei Zhen, an exiled Qin noble who went to the Jin state and received a fief from Duke Ping, the Jin ruler.
