Fa Zheng

Fǎ Zhèng was an advisor for Shu during the Three Kingdoms era of China. He was born in 176 AD during the fall of the Han Dynasty. He was originally a subordinate of Liu Zhang but later helped with Liu Bei's invasion of the region that would become known as Shu. After the death of Pang Tong, Fa Zheng was arguably the greatest tactician in Shu-Han and was the most reliable vassals for Liu Bei. At Liu Bei's invasion of Hanzhong, he acted as military advisor for Liu Bei, then, successfully defeated Cao Cao's army and seized Hanzhong. When he died in 220 because of an illness, Liu Bei was said to weep day after day for him. Then Liu Bei gave him the Posthumous name the Maruquis of Wing. In addition, he is the only person who was sent a posthumous name by Liu Bei. According to Zhuge Liang's opinion, if Fa Zheng were still alive, he would have prevented Liu Bei from attacking Sun Quan in the aftermath of Guan Yu's death, but if Liu Bei had gone anyway, he would not have lost the Battle of Yiling.
