Западная Вэй
Despite the strong personal relationship between Gao Huan and Hou Jing, however, Hou had little respect for Gao's oldest son and heir apparent Gao Cheng, once making the comment to another friend of his and Gao Huan's, Sima Ziru (司馬子如), that he would remain loyal if Gao Huan were still alive, but that he could not serve together with the "Xianbei boy" (i.e., Gao Cheng) if Gao Huan died. (Gao Huan was ethnically Han, but was acculturated in the Xianbei ways.) In late 546, believing that Gao Huan was dead or near death, Hou began to prepare to rebel, and he did so in spring 547. He first surrendered the 13 provinces that he commanded to Western Wei, but subsequently also surrendered to Liang. Both Western Wei and Liang sent troops to support him. Before Western Wei and Liang troops could arrive, Eastern Wei forces commanded by Han Gui (韓軌) surrounded him at Yingchuan (潁川, in modern Xuchang, Henan). Western Wei forces commanded by Wang Sizheng (王思政) soon arrived, and Han withdrew. Wang, not believing that Hou actually intended to become a loyal Western Wei subject, secured four provinces that Hou was willing to give up control to. Meanwhile, Emperor Wu of Liang was greatly pleased by Hou's surrender, and launched a major attack commanded by his nephew Xiao Yuanming the Marquess of Zhenyang, intending to relieve the pressure on Hou by opening another front to the east. Soon, Yuwen Tai demanded that Hou visit the Western Wei capital Chang'an to pay homage to Emperor Wen of Western Wei, to show his good faith. Hou refused, and he tried to persuade a number of Western Wei generals to join him, but only Ren Yue (任約) did, with a minor army. The rest of the Western Wei forces withdrew their support from Hou and merely defended the provinces that Hou had given up.
