Liu Yin
Liu Chonggui had, in or around 894, commissioned Liu Yin as the defender of Heshui Base (賀水鎮, in modern Nanning, Guangxi), and then as the prefect of Feng Prefecture (封州, in modern Zhaoqing, Guangdong). Therefore, after Liu Yin subsequently became the military governor of Qinghai, first in an acting capacity in 901 and then officially in 904, Liu Yin, in showing gratitude to Liu Chonggui, treated Liu Jun with respect. He invited Liu Jun to serve on his staff, serving with Li Yinheng and Ni Shu, often consulting them on key decisions.
