Yu Liang

Yu Liang (庾亮; 289^[1] – 14 February 340^[2]), courtesy name Yuangui (元規), formally Marquess Wenkang of Duting (都亭文康侯), was a Chinese military general and politician of the Jin dynasty 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.

^ According to Yu Liang's biography in Book of Jin, he was 52 (by East Asian reckoning) when he died. (咸康六年薨，时年五十二。) Jin Shu, vol.73. Thus by calculation, his birth year should be 289.
^ According to volume 96 of Zhizhi Tongjian, Yu Liang died on the gengzi day of the 1st month of the 6th year of the Xiankang era of Emperor Cheng's reign. This corresponds to 14 Feb 340 on the Julian calendar. ([咸康六年]春，正月，庚子朔，都亭文康侯庾亮薨。), Zizhi Tongjian vol.96
