Liu Yin (190 – 269), courtesy name Xiuran, was a military officer of the state of Shu Han in the Three Kingdoms period of China. Life. Liu Yin was born in Chengdu, the capital of Yi Province (covering present-day Sichuan and Chongqing). During his youth, Liu Yin's name became famous along with those of Du Zhen (杜禎) and Liu Shen (柳伸) who were of the same commandary as he. He was known as someone who was forthright, sincere and bright. He was a generous man to his friends. Thanks to those qualities, he became a  successful military officer. Later, he was a supporter of Grand General Jiang Wei and accompanied him in his many northern campaigns. During these campaigns, Liu Yin showed skills in improvising plans, would fearlessly charge through the enemy lines and break their formations. His valour and cleverness made him popular in the army and a champion among the soldiers. For his exploits, he was nominated as General of the Standard (牙門將), Administrator of Ba commandary (巴郡太守) and Cavalry Commandant (騎都尉). Later, he was summoned back to be the new Garrison Commander of Huangjin (黃金圍督) in Hanzhong commandary. During Cao Wei's  invasion of Shu Han in 263, Zhong Hui led his army to the Hanzhong region where most of the local garrisons surrendered to him without opposition. Only Liu Yin refused to surrender; he held onto his strong position and would not be displaced. Still, Zhong Hui's subordinate generals kept up the attack, but they were beaten back and could not capture his garrison. After his abdication to Deng Ai, Liu Shan sent Liu Yin a handwritten order commanding him to surrender and only then did he surrender to Zhong Hui. Sima Zhao heard of this, was greatly impressed and  came to deeply respect Liu Yin for his loyalty. One year later, in 264, Liu Yin was summoned to Hedong where he was appointed as a Consultant Gentleman (議郎). When Sima Yan established the Jin dynasty, he assigned Liu Yin to be the Administrator of Xihe (西河太守). Liu Yin stayed in that office for the next three years before resigning his commission on account of his old age. Before his death, he asked for his remains to be sent back to his homeland in the Shu region. He died among his family at the age of 79 years old. Liu  Yin's elder son, Liu Chong (柳充) later became Prefect of Liandao. While his younger son, Liu Chu (柳初) was recommended as an abundant talent candidate.
