Liu Bang took more than 300 people to Lishan as coolies. However, it rained heavily for several days, which delayed the trip. According to the law of Qin dynasty, people have to be beheaded, so most people fled. Brother Bong was depressed, so he went to drink too much and fell asleep. When he woke up, he found a white snake beside him and killed it in panic. At this time, those people who came with Liu Bang also came and saw it. Just then, an old lady appeared and said that my son Betty had died and was killed by Chi Di. So Liu Bang called himself the son of Chi Di. Because of the delay in the trip, everyone had to die, and there was no choice but to rebel. But after the uprising, Liu Bang took refuge in Xiang Liang, so he still used the banner of recovering Chu.
