Judging from the evolution of dragons, the first dragon was not a dragon, but a coke, which became a dragon thousands of years later. At that time, people thought that dragons were the most lewd, that is to say, dragons not only had nine sons, but probably more. People only take the most representative Jiuzi as an example.
The saying "Long Sheng Jiu Zi" originated from the Ming Dynasty. It is said that the Ming emperor couldn't figure out the name of Jiuzi, so he asked Li Dongyang, a great scholar at that time, to make up the name of Jiuzi. It's good to be an emperor. Say a word casually and countless people will run errands for it.
The emperor's casual words stumped the ministers at that time. College students began to rummage through the records of Nine Children of the Dragon in the sea of books, and it was precisely because of this that people knew the allusions of Nine Children of the Dragon. Li Dongyang, a great scholar, replied with the emperor as the representative, that the dragon gave birth to nine sons, each of which was unsuccessful and each had its own strengths. Prison cows like music, so now the animal shape carved on Hu Qin's head is prison cows.
I love singing all my life, so people carve its image on the clock. Wuzi Sister-in-law Suān ní, who lives a comfortable life, prefers quietness to movement, so people put it in front of the Buddha to offer sacrifices. Overlord, like to bear the burden, in ancient times, people carved stone tablets based on the image of overlord.
Armadillos like to argue about the truth. In ancient times, lions carved on both sides of the prison were its image. The coffin is most shaped like a dragon, so it is carved on a pillar. Chρwěn is a god beast who likes to swallow things. People carved it on the top of the palace to resist disaster.
In fact, these were compiled by Li Dongyang and other university students in order to cope with the Ming emperor, and later by a butler. Naturally, some people are sought after and some people believe it. Since the Ming dynasty, it has been handed down from generation to generation, and the animal shapes carved with Jiuzi at that time have also been handed down with the legend.
