Huaxia originated from Huaxu, and covers most of Henan Province and the middle and lower reaches of the Yellow River including parts of southern Hebei Province, southern Shanxi Province, eastern Shaanxi Province and western Shandong Province around Henan. Huaxia is also called "Hua", "Xia" or "Zhuxia" etc. The word "Huaxia" was first seen in "Shangshu·Zhoushu·Wucheng": "Huaxia is barbaric and will not lead others."
It is also believed that "Xia" comes from the Xia River (i.e. the Han River) In ancient books, "Hua" and "Xia" are regarded as the Central Plains, and the four directions are called "Yi, Man, Rong and Di". Hua and Xia used to be interchangeable, and the two words are tautological. Hua means Xia. "Zhonghua" is also called "Zhongxia". For example, in "Zuo Zhuan", Confucius said in the 10th year of Dinggong's reign: "If the descendants do not seek Xia, the barbarians will not disrupt China." The "Hua" here is also "Xia". Confucius regarded "Xia" and "Hua" as synonyms. Around the time when "Shang Shu" was compiled, "Hua" and "Xia" began to be used together in ancient Chinese books, collectively referred to as "Hua Xia".
Kong Yingda, a Confucian scholar of the Tang Dynasty, said in "Chun Qiu Zuo Zhuan Zhengyi": "China has great etiquette, so it is called Xia; it has the beauty of uniforms, so it is called Hua." This means that because China is a country of etiquette, it is called "Hua". It is called "Xia", and "Xia" means elegance; Chinese people's clothes are very beautiful, pretending to be "hua". The word Huaxia is not only geographical, but also has a deeper value in terms of cultural deposits.
The more famous Chinese ancestors include: Chao, Suiren, Fuxi, Shennong (Yandi), Huangdi (Xuanyuan), Yao, Shun, Yu, etc. Among them, according to the Chinese History Table, the Youchao family ranks first among the five clans and is known as the "first humanistic ancestor" of China. The Chinese ancestors left numerous civilization sites in the Yellow River and Yangtze River basins.
