庾亮
Yu Liang (庾亮; 289–340), 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 (266–420) 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.
