In June, Wu Wu, An Zhongrong caught Khitan envoy Zhai Ci and sent cavalry to raid the southern border of Youzhou. He stationed his troops in Boye and submitted a memorial to say that Tuyuhun, the two Turkic tribes, Hun, Qi and Shatuo each led their own groups to submit; Dangxiang and others also sent envoys to surrender the credentials of the official positions appointed by Khitan, and complained that they were harassed and abused by Khitan. They also said that since February, Khitan had ordered their troops to prepare strong soldiers and horses, intending to invade south in autumn. They were scared that heaven would not protect them so they would be doomed along with Khitan. They were willing to prepare 100,000 troops to attack Khitan together with Jin.
