Liu Zhiyuan
At the same time, Shi sent Liu Zhiyuan to Hedong to serve as its military governor, to also monitor the situation with An. Liu enticed the Tuyuhun chieftain Bai Chengfu (), who had previously submitted to An Chongrong, into joining the Hedong army with his tribesmen. That, and the failure of Dada and Qibi () tribesmen to join An Chongrong (as he had claimed that they would), hampered the impact of An's public pronouncements.
