About 2070 BC, Qi established the Xia Dynasty, and the Shang Dynasty was established 1600 years ago. Before 1046, the Zhou Dynasty was established. Since the Western Zhou Dynasty, various ethnic groups and tribes in the territory have been continuously integrated, forming the Huaxia nationality in the Yellow River basin and the Chu nationality in the Huaihe River, Surabaya River, Yangtze River and Hanshui River basins. During this period, Huaxia and Chu ethnic groups gradually formed and became the predecessors of modern Han nationality, which was different from many ethnic groups such as Yi, Man, Rong and Di, but the distinction between Hua and Yi was not very strict at this time.
During the Spring and Autumn Period, Huaxia people further integrated with the surrounding ethnic groups, and Huaxia people gradually integrated with Chu people and Qin people. During the Warring States Period, the vassal states of China fought against each other, and the Yi, Man, Rong and Di who entered the Central Plains gradually merged with the Huaxia nationality, forming a relatively stable nation. At this time, the activity area of Huaxia nationality also expanded to the middle and lower reaches of Liaohe River, Taohe River Basin, Sichuan Basin, south of the Yangtze River and other places.
Qin destroyed six countries and unified China. In just over ten years, under the leadership of Chu people such as Chen Sheng, Guangwu, Xiang Yu and Liu Bang, the Qin Dynasty perished. Subsequently, Liu Bang and Xiang Yu, both Chu people, competed for supreme sovereignty. Liu Bang won, and the Han Dynasty was established and ruled China for more than 400 years. During this period, the territory of China expanded unprecedentedly, with Chu and Huaxia in the pre-Qin period as the core, and some tribes of Qiang and Xiongnu were integrated, forming the Han nationality.
