Han nationality is a noun corresponding to Xia nationality, and it is a noun that divides two tribes in ancient mythology. In the Zhou Dynasty, people who followed the etiquette and kept the etiquette and righteousness were called Han, Han, Xia and Xia, and were generally called Zhu Hua and Zhu Xia. In ancient books, China and Xia are regarded as the Central Plains, while Yi and Yi are regarded as the four directions. China is also called China, Midsummer, Middle-earth and China. The area with high culture is called Xia, and the people or nations with high civilization are called Hua. Over time, China has become synonymous with the Chinese nation.
Hua and Xia are homophones in ancient times, and Ben are common to each other. In Zuo Zhuan, the phrase "Chinese people don't seek summer, and foreigners don't mess with China" is synonymous with China and Xia, and China is summer. China is also called midsummer, and Confucius regards midsummer as a synonym for Huawei. In Oracle Bone Inscriptions, the word "Hua" occupies a very lofty position. About the Spring and Autumn Period, China ancient books began to use "Hua" and "Xia" together, collectively referred to as Huaxia nationality.
Huaxia, commonly known as Huaxia, is said that about 5000 years ago, there were many tribes between Huashan and Xiashui in the middle and lower reaches of the Yellow River Basin, among which the most important ones were the later Yan Di tribe and the Huangdi tribe. The Chinese nation formed by the integration of Yanhuang tribes is the descendants of China. Since the Han dynasty, it has also been called the Han nationality, but the title of Huaxia has not disappeared, but has continued to this day. Before the twentieth century, the most commonly used appellation was Huaxia people.
