In the pre-Qin period, surnames were not unified. Men use their surnames, and women use their surnames. The winning surname is Qin. Qin was a vassal state of China during the Spring and Autumn Period and the Warring States Period. Qin people are a branch of Chinese people who moved westward. Its monarch won the surname (after the surname), and it is said that Zhou was enfeoffed as a vassal of the Zhou Dynasty because Qin Zu was good at raising horses. 770 years ago, Qin Xianggong was made a vassal for escorting Zhou Ping to the East. After the founding of People's Republic of China (PRC), Qin occupied the territory of the former Zhou Dynasty in Shaanxi, and was occupied by Rong and Di. Since 677, Qin has established its capital in Yong for nearly 300 years. Yongcheng has a palace area, a residential area, a burial area for scholars and China people, and a cemetery for Qin Gong. The original territory of the State of Qin was in the western part of Shaanxi Province today, belonging to the marginal zone of China at that time. Qin people are good at fighting, but Qin has always been a weak country until the early Warring States. Perhaps it is because it is remote and has not been valued by other countries. In the early Spring and Autumn Period, it was a humble country. It was not until Qin Mugong's time that he participated in the Central Plains hegemony and became a second-class power after Jin, Chu and Qi. In terms of science and technology, culture, etc., Qin was also relatively backward in the early Warring States period. This situation was not changed until the Shang Yang Reform 36 1 year ago. From then on, Qin began to become strong. In the first 325 years, Qin Huiwen was king. Before 3 16, Qin destroyed Shu, and since then Qin has officially become a big country. Qin Shihuang ascended the throne in the first 246 years, took power in the first 238 years, and began his conquest of the six countries. From the Qin Dynasty's elimination of Korea 230 years ago to the unification of China 22 1 years ago.
