In July of the first year of Qin Ershi, Chen Sheng and Guangwu led the troops with 900 troops and stationed in Yuyang. Bobby Chen, a native of Yangcheng, worked as a servant in his early years. Uncle Wu Guangzi is a native of Yang Xia and a poor farmer. They went to osawa Township, but Bobby Chen was blocked by heavy rain, so they couldn't arrive on time. According to Qin law, if it expires, it will be beheaded. Chen Sheng launched a garrison uprising with the tactics of "the fish is full of Dan" and "the fox is on fire", and put forward the slogan of "Great Chu Prosperity, Chen". Chen Sheng encouraged the guards to say, "When a strong man dies, he is himself. If he dies, he will raise his name and the prince will have seeds! " So he established himself as a general, took Guangwu as his surname, and called on the masses to revolt in the name of Fuxi, the eldest son of Qin Shihuang, and Xiang Yan, the general of Chu.
