Meanwhile, Gao Cheng started peace negotiations with Emperor Wu, offering to return Xiao Yuanming and intending to cause Hou to become apprehensive. Hou Jing opposed peace with Eastern Wei, worried that he would be betrayed if there was peace between the two states. Emperor Wu made a personal guarantee that he would not betray Hou—but Hou then tested Emperor Wu by forging a letter from Gao Cheng, proposing an exchange of Xiao Yuanming for Hou. When Emperor Wu, under advice from Zhu Yi—a key assistant to Emperor Wu whom Hou had bribed, hoping that he would discourage peace talks, but whose opinion was unchanged by Hou's bribes—wrote back, "If you return Xiao Yuanming in the morning, I will deliver Hou Jing in the evening," Hou was incensed. He wrote a harshly worded accusation to Emperor Wu, who responded with meek words that failed to persuade Hou against a rebellion. Meanwhile, Hou entered into secret negotiations with Emperor Wu's nephew Xiao Zhengde the Prince of Linhe, offering to make the ambitious Xiao Zhangde emperor, and Xiao Zhengde agreed to assist him. At the same time, despite warnings from Yang Yaren (whom Hou had tried to persuade to join in his plans) and Xiao Fan (蕭範) the Prince of Poyang, Emperor Wu failed to take precautions against a Hou rebellion.
