Wei Chu 魏處 was an advisor to the counsellor-in-chief of Qi 齊, Lord Mengchang 孟嘗君, during a war between Qi and Yan 燕. The king of Qin wanted the state of Zhao 趙 to support Yan, which Qi wanted to prevent. Lord Mengchang therefore sent Wei Chu to Zhao. Wei Chu suggested to Li Dui 李兌, a general of Zhao, not to engage in the conflict because Zhao would profit in any case.
