Gongsun Shu 公孫戍 was a retainer of Lord Mengchan 孟嘗君 and accompanied him to Chu 楚. The king of Chu presented the king of Qi 齊 a bed made of ivory. The king ordered Deng Tu 登徒 to bring the present to Qi, but Deng was too afraid to take over the responsibility for such a precious object. Instead, Deng would present an ancient sword to Gongshun Shu if he would be spared to transport the bed. Gongsun persuaded Lord Mengchang not to accept the luxury item, and at the same time was given the sword by Deng Tu.
