Zhou Yu (, ) (175–210), courtesy name Gongjin (), was a Chinese military general and strategist serving under the warlord Sun Ce in the late Eastern Han dynasty of China. After Sun Ce died in the year 200, he continued serving under Sun Quan, Sun Ce's younger brother and successor. Zhou Yu is primarily known for his leading role in defeating the numerically superior forces of the northern warlord Cao Cao at the Battle of Red Cliffs in late 208, and again at the Battle of Jiangling in 209. Zhou Yu's victories served as the bedrock of Sun Quan's regime, which in 222 became Eastern Wu, one of the Three Kingdoms. Zhou Yu did not live to see Sun Quan's enthronement, however, as he died at the age of 35 in 210 while preparing to invade Yi Province (modern Sichuan and Chongqing). According to the "Records of the Three Kingdoms", Zhou Yu was described as a tall and strong man with beautiful appearance. He was also referred to as "Master Zhou" ("zhoulang" 周郎). However, his popular moniker "Zhou the Beautiful Youth" ("meizhoulang" 美周郎) does not appear in either the "Records" or the 14th-century historical novel "Romance of the Three Kingdoms". Some Japanese literary scholars such as Yoshikawa Eiji and Koide Fumihiko believe that this was a later invention by Japanese storytellers.
