Hanzhong Campaign
In 219, after Liu Bei emerged victorious in the Hanzhong Campaign, he declared himself "King of Hanzhong" () and appointed Fa Zheng as the Prefect of the Masters of Writing () and General Who Protects the Army (). Fa Zheng died in the following year at the age of 45 (by East Asian age reckoning). Liu Bei cried for days when Fa Zheng died and awarded Fa the posthumous title "Marquis Yi" (), which literally means "marquis of the flank". Fa Zheng's son, Fa Miao (), received the title of a Secondary Marquis () and served as a Commandant of Equipage () and the Administrator of Hanyang Commandery () in the state of Shu Han, which Liu Bei established in 221.
