An Chonghui quickly became the most powerful advisor for Emperor Mingzong, and, as Emperor Mingzong was illiterate, he relied on An to read to him the petitions coming from throughout the realm, although An, realizing that he was also not capable of handling all these petitions, recommended the imperial scholars Feng Dao and Zhao Feng to serve in that role. As chief advisor, however, he quickly developed a rivalry with the chancellor Ren Huan, as Ren was putting much of his own imprint on the governance, drawing An's jealousy. Meanwhile, Emperor Mingzong wanted to reward An by commissioning him as the military governor of Shannan East Circuit (山南東道, headquartered in modern Xiangyang, Hubei) and serving remotely (with an acting military governor at the circuit itself). An believed that Shannan East was too important of a circuit to lack an actual military governor at the circuit, and therefore declined; Emperor Mingzong subsequently agreed.
