Tian Xu 田需 was a counsellor-in-chief to King Ai of Wei 魏哀王 (r. 318-296). When the nobleman Guan Yan 管燕 was demoted from office by the king of Qi 齊, he had to leave the country, but nobody of his retainers would assist him to obtain a new position in another state. Alone Tian Xu dared criticizing Guan Yan for his disrespectful treatment of his retainers.
