Leng Xiang 冷向 was a high minister in Qin 秦. Once Zheng Qian 鄭強, an exiled minister of Han 韓, wanted to take revenge and offered a bribe to the king of Qin to attack its own ally, the state of Han. Leng Xiang suggested to him to cause internal quarrel between the counsellor Prince Gong Shu 公叔 and his competitor to the throne, Prince Ji Se 幾瑟 (Ji Shi 蟣虱), who dwelled as a hostage in Chu 楚. Fearing a conflict with Chu, Han would not attack Chu, and this would cause the king of Qin to doubt the sincerity of Han.
