Legend has it that after Nuwa created man, human beings were not very peaceful. Because the number of animals in ancient times was far more than that of humans, humans living on the ground were often attacked by animals and animals, and they were always in danger.
Due to the harsh living environment, some humans began to migrate north. They came to the middle reaches of the Yellow River (around present-day Shanxi and Shaanxi), imitated the survival methods of rodents, made holes in the slopes of the Loess Plateau, lived inside, and blocked the openings with stones or branches, which made it much safer. But there are still many people who remain in the south, preferring to continue to live dangerous lives than to endure the cold climate of the north.
At this time, in Cangwu, south of the Nine Ridges Mountain, there was a Nest Clan born. Legend has it that he once swam through the Immortal Mountain and received guidance from the Immortals, so he had a very high degree of wisdom. He was inspired to see birds nesting in trees and was the first to invent the "nest dwelling". He taught people to build houses with branches and rattan on tall trunks, and the branches covered the surrounding areas and roofs of the houses tightly, both to shield them from the wind and rain and from attacks by animals. Since then, people have said goodbye to their previous dangerous lives and no longer have to live in fear.
People are very grateful to the Youchao clan, elect him as the tribal chieftain, and honor him as the Youchao clan, after the Youchao clan became the tribal chief, they did many good things for everyone. Soon after, various tribes spread his oral deeds, and his reputation spread throughout the land of China. The people of the tribes considered him to be of high moral standing and possessing the talents of the Holy King, so they elected him as the chief chief, that is, the chief of the headquarters of the tribal alliance, and honored him as the "Nest Emperor".
Legend has it that after the Chao clan came to power, the capital was close to the northern holy land of Shilou Mountain (northeast of present-day Xing County, Lüliang City, Shanxi), and the Chao clan had people dig a cave on the mountain, and he lived in the cave to handle government affairs. Therefore, Shiloushan was called the imperial capital of the Chao clan by later generations.
During the Chao period, the land of China had entered the stage of matrilineal clan communes. Hunting and fishing are the main social activities of men, while women collect wild vegetables and dig up roots of plants. At that time, the form of human marriage also changed greatly, not only to eliminate the intermarriage relationship between relatives, but also to prohibit intermarriage between men and women of the same generation within the same clan, and could only choose men and women in other clans to marry, which was extra-tribal group marriage in matrilineal clan society.
