Tian Jun
In 902, Qian Liu was attacked by Tian Jun, the military governor of Ningguo Circuit (寧國, headquartered in modern Xuancheng, Anhui), who himself was a vassal of the major warlord Yang Xingmi the military governor of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu). His headquarters at Hang Prefecture (杭州) came under Tian's siege. While Yang - not wanting to see Tian becoming overly powerful - ordered Tian to withdraw, Tian extracted the price of having Qian send a son to return with him to Ningguo to serve as hostage (with Tian agreeing to give a daughter to him in marriage). Qian's son Qian Chuanguan volunteered, even though the situation was considered extremely perilous. Hu and another soldier, Dai Yun (戴惲), served as Qian Chuanguan's attendants on this journey, putting themselves in the same risks that Qian Chuanguan was under. After Tian rebelled against Yang and was killed in 903, Qian Chuanguan returned to Qian Liu's domain; presumably, Hu (and Dai) also accompanied him in his return.
