Qian is a Goa'uld and is one of the Goa'uld System Lord Yu's sons. He came into his father's service shortly after he received his first host. Qian is ambitious, greedy and ruthless. Fortunately for Yu's regime, he is neither subtle or patient. Yu placed him under constant surveillance by his Jaffa. His First Prime has standing orders to execute Qian should he attempt any form of takeover.
Qian has a small cadre of followers, two of whom are his biological family, who look up to him as a potential ruler. Chiang and Tan-su are his siblings, and they are both ruthless Goa'uld. Yu does not know of their quiet support for Qian and would probably have them summarily executed if he heard of it. (RPG: "Living Gods: Stargate System Lords")
