The book Chronicle of Bamboo Slips: A Journey to Midsummer has such a record: "That is, the emperor ... rocks, rocks, sings Jiu Shao, and all animals dance." As early as the Three Kingdoms period, there was a five-animal play invented by the imperial doctor Hua Tuo, that is, imitating the demeanor and movements of animals in order to achieve the purpose of health preservation. In early society, animals had power that humans didn't have, so people could not help but worship some animals. This is also why the totems of some tribes are animals. People deliberately imitate animals, which means they gain the power of animals. Therefore, King Qingyang's "leopard hat" means that he has the power of a leopard and represents his courage and perseverance.
There is also the ancestral motto of Qingyang tribe that "the youngest son keeps his job", which means that no matter whether Asu (played by Liu Haoran) finally takes over Qingyang Department in this life, he is the youngest son of Qingyang Grand King, which also means that his position is higher than his brothers. This ancestral motto of Qingyang Department is actually based on history, not nonsense.
In the Central Plains of ancient China, there has always been a saying that princes grew up in power, which is also commonly known as the eldest son inheritance system. However, in many ethnic minorities, the inheritance system is just the opposite of the Central Plains, and the youngest son inheritance system is implemented. For example, before the Yuan Dynasty, most brave Mongolians followed this form of inheritance. The concept of "self-reliance and self-improvement" gradually replaced the concept of "the younger son keeps his job", which was also gradually formed from Genghis Khan.
