Who destroyed the state of Qin?

In July of the second year (209 BC), the peasant worker uprising led by Chen Sheng and Guangwu was sentenced to death for dereliction of duty. The anti-Qin struggle was then led by Xiang Yu and Liu Bang respectively, and attacked Qin in the west. At this moment, Zhao Gao killed Prime Minister Reese and II, and made Sun Ziying the first emperor of Qin. In 207 BC, Xiang Yu defeated Qin Jun, and Qin Jun was wiped out in Julu War ... In 206 BC, Liu Bang entered the customs, Zi Ying left the city, and the Qin Dynasty perished.

The title of Qin Dynasty comes from place names. According to historical records, the ancestors of the Qin Dynasty were sages Hao Tao and Boyi. They were originally descendants of Shao Hao, an ancient tribal leader, and their surname was Wang. For me, Zhao Fu was a Zhou royal family, who put down Xu Qianli's rebellion and sealed it in Zhao Cheng. His clan is Zhao (in the pre-Qin era, "surname" was only the source, mostly used for offering sacrifices and addressing women, while "surname" was a branch of the family, addressing men), so "Zhao" was also one of the pronouns of Qin.

In the early days, Qin people were named Qin land by Zhou for their contributions to raising horses for the Zhou royal family, and Qin became their official family name. During the ruling period, dogs invaded Haojing, which was officially made a vassal state because of its meritorious service in defending the Zhou royal family, and Qin became the national title. Before Qin Shihuang unified China, Qin was only a vassal state. After reunification, the name of a vassal state changed to that of a dynasty in China. Because the ruler's surname is Sheng, it is also called Sheng Qin.
