Bai Qi
Bái Qǐ, also known as Bo Qi, (Chinese: 白起) (died 257 BC) was a military general of the State of Qin during the Warring States Period of Chinese history. Born in Mei (now Mei County in Shaanxi Province), as commander of the Qin army for more than 30 years, Bai Qi was responsible for the deaths of a total over 890,000 enemy soldiers, earning him the nickname Ren Tu (人屠 literally: human butcher). He seized more than 73 cities from the other six Warring States in the Warring States Period and to date no record has been found to show that he suffered a single defeat throughout his military career.
