If you don't agree with a word, what other legends about dragons are not well known to the public?

Legend has it that a long time ago, there were many tribes in China, and each tribe had its own mascot. One of them is a snake. He is very strong. He recovered all the tribes one by one, and every time he recovered one, he added a part of his own tribal mascot to his mascot, so there was the dragon now, which was composed of scales, feet and claws of a snake.
