Bai Qi (Chinese: 白起; c.– 257 BC), also known as Gongsun Qi (公孙起), was a military general of the Qin state in the Warring States period of China. Born in Mei (present-day Mei County, Shaanxi), Bai Qi served as the commander of the Qin army for more than 30 years, being responsible for the deaths of over one million, earning him the nickname Ren Tu (人屠; lit. 'human butcher'). According to the Shiji, he seized more than 73 cities from the other six hostile states, and to date no record has been found to show that he suffered a single defeat throughout his military career. He was named by Chinese historians as one of the four greatest generals of the late Warring States period, along with Li Mu, Wang Jian, and Lian Po.
