Yu Liang

Yu Liang (庾亮; 289–340), courtesy name Yuangui (元規), formally Marquess Wenkang of Duting (都亭文康侯), was a Jin Dynasty (265–420) official and general who impressed many with his knowledge but whose inability to tolerate dissent and overly high evaluation of his own abilities led to the disastrous revolt of Su Jun, weakening Jin's military capability for years.

When Yu Liang was young, he was known for his skills in rhetoric and knowledge in the Taoist philosophies of Lao Tsu and Zhuangzi. When he was just 15, he was invited by Emperor Huai's regent Sima Yue the Prince of Donghai to be on his staff, but he declined, instead staying in Kuaiji Commandery (the southern shore of Hangzhou Bay) with his father Yu Chen (庾琛), the governor of Kuaiji.

After Sima Rui the Prince of Langye was posted to Jianye as the military commander of the area south of the Yangtze in 307, he invited Yu Liang to serve on his staff, and during that time, he became impressed by Yu's abilities and solemn attitude, and he took Yu Liang's sister Yu Wenjun to be his son Sima Shao's wife. It was while in Sima Rui's service that Yu was created the Marquess of Duting. Later, after Sima Rui claimed imperial title after Emperor Min's death in 318 (as Emperor Yuan), Yu, along with Wen Jiao, were friends and key advisors of Sima Shao, who became crown prince. After Emperor Yuan's death and succession by Crown Prince Shao (as Emperor Ming), Yu continued to be a key advisor, and was heavily involved in his planning against and subsequent defeat of the warlord Wang Dun's forces in 324. Yu declined all monetary awards and the title of the Duke of Yongchang, however.
