Du Fuwei, whose real name is Du Yao (杜尧), is a native of Zhangqiu County, Qizhou, who was poor and poor when he was young, and was not good at managing his livelihood, so that he could not support himself, so he often stole things to make a living. Du Fuwei had a life and death friend called Fu Gong Wei, Fu Gong Wei's aunt to shepherd sheep as a profession, so Fu Gong Wei often stole the aunt's sheep to help Du Fu Wei, after being discovered by the aunt, they sued the officials, helplessly the two died in the mountains, and gathered a group of people to form a gang of robbers, at this time Du Fu Wei was only sixteen years old. In the ninth year of Daye, Du Fuwei and Fu Gongrui came to Changbai Mountain to organize mountain thieves to join a rebel army, officially launched an uprising, and because of his bravery in battle, Du Fuwei was pushed as the leader and began his hegemony.

After the annexation of Miao Haichao, Zhao Shaojin and other small rebels, Du Fuwei's strength increased greatly, and in the eleventh year of The Great Cause, Li Zitong, a donghai man, led more than 10,000 people to vote, but soon Li Zitong suddenly launched a mutiny and tried to annex Du Fuwei's territory, Du Fuwei was seriously injured in pursuit, and his strength was greatly damaged, and then Du Fuwei was defeated by the Sui army, and du Fuwei lost the strength to fight for hegemony, so he had to go around guerrilla warfare and constantly absorb displaced people into his own ranks, and after half a year, the number of troops expanded to tens of thousands, It also controlled Liuhe County near Jiangdu as a base area. In the twelfth year of Daye, Yang Guang avoided jiangdu in the south due to many troubles in the north, and due to successive years of war, coupled with the oppression of the government and the huge pressure of Emperor Zhao's southern tour, the people were displaced, and Du Fuwei took this opportunity to absorb a large number of subordinates, and his power quickly expanded.

After his growth, Du Fuwei first defeated the Sui general Chen Ling, occupied important towns such as Gaoyou and Liyang, and declared himself the governor; Then he reformed taxes on his own territory, charging only very low taxes to the people in the territory, and severely punishing corrupt officials, so he was very supported by the people. In the fourteenth year of Daye, Yu Wenhua and launched a mutiny to kill the Sui Emperor, Du Fuwei refused Yu Wenhuahe's offer, and instead declared himself a vassal to Yang Dong, the Yue king of Luoyang, and was made the King of Chu, and the grand governor of Dongdao. In the second year of Wu De, Du Fuwei announced his surrender to the Tang Dynasty, was named huainan pacification ambassador, and was later promoted to southeastern province Xingtai and Shangshu Ling, and was crowned king of Chu, and in the third year of Wu De, he was in charge of the military forces south of Jianghuai, changed the title of King of Wu, and gave the surname Li, at this time, although Du Fuwei nominally surrendered to the Tang Dynasty, Li Yuan was powerless to interfere in Du Fuwei's affairs, so in fact there was not much difference between him and the hegemon of one side. It was also in the third year of Wude that Du Fuwei defeated Li Zitong and won the land of Jiangxi, and in the fourth year of Wude, Du Fuwei defeated Li Zitong again, and Li Zitong himself surrendered and was taken prisoner of Chang'an, and was placed under house arrest. Subsequently, Du Fuwei sent troops to eliminate other independent forces between Jianghuai and Huaihuai, and completed the unification of Jianghuai, with all the land in Huainan and Jiangdong.
Tang Taizong Li Shimin
In the fifth year of WuDe, Du Fuwei invited himself to join the dynasty to avoid suspicion, and was crowned as the Crown Prince Taibao, ranking above Li Yuanji the Prince of Qi, becoming the fourth person in the Tang Dynasty after Li Yuan, Li Jiancheng, and Li Shimin, but after Du Fuwei left, the Jianghuai army was in turmoil. Fu Gong Was Du Fuwei's neck-and-neck friend, known as Fu Bo in the army, had great influence, and as the team continued to grow, the relationship between the two also cracked under the inducement of power. In order to prevent Fu Gongwei from seizing power, Du Fuwei stripped him of his military power and gave him a high but powerless vacant post, so after Du Fuwei entered the capital, Fu Gong and Zuo Youxian launched a mutiny, and in the sixth year of Wu De declared independence from Li Tang, Fu Gong was called emperor and the founding name was Song. Under the influence of Fu Gong's rebellion, Du Fuwei, who was in Chang'an, was highly suspected, and finally died in fear in the seventh year of WuDe, at the age of forty-one. After Du Fuwei's death, Li Yuan stripped him of his official title and had no family members until Li Shimin ascended the throne, and did not restore his reputation until li Shimin ascended the throne, and was buried with the ceremony of a duke.
