Xiang Yu then threatened to kill Liu Bang's captured father and wife and have them cooked over a fire, to force Liu Bang to surrender. Liu Bang simply replied that since the two had been named 'brothers' (during the earlier years of the revolt against Qin Dynasty) he would be effectively cooking his own father, and that Xiang Yu should not forget to send him a cup of 'their' father's flesh to share as good brothers, but Xiang Yu still did not kill them. At one point, Xiang Yu was about to capture Liu Bang. Finally, Liu Bang agreed with everything that Han Xin requested, and Han Xin finally agreed to help. Later, with the arrival of Han Xin, Liu Bang was able to convince Xiang Yu to agree to a peace treaty. At the end, both parties agreed that the two countries of Han and Chu could co-exist peacefully. Liu Bang's father and wife were returned to Liu Bang. Then, in October 202 BC, Xiang Yu started to move his forces back east.
