Tian Jian 田簡 was a retainer of Sima Xi 司馬憙 from the state of Zhongshan 中山. There were discrepancies between Sima Xi and Princess Yin Jian 陰簡, which Tian Jian tried to smoothen. He suggested Sima Xi to praise the beauty of Yin Jian in a conversation with the embassador of Zhao 趙. To the latter, he was to propose a marriage with the king of Zhao. Although the rift between the two persons was closed, the planned marriage was never arranged.
