Dragon, in the myths and legends of China, is a magical animal, with the image of snake body, lizard legs, talons, snake tail, antlers, fish scales, whiskers on the mouth and beads under the forehead. According to Shan Hai Jing, Xia Houqi, Ru Shou and Ju Mang all "rode the rain dragon". There are other secretaries, Zhuan Xu, Lapras and the Four Seas, Di Ku, Spring and Summer, Lapras. The predecessors divided dragons into four types: those with scales, those with wings, Ying Long, those with horns and those without horns. Some people think that this is the image formed by the totem of each clan after the ancient Yanhuang unified the tribes in the Central Plains. Legend has it that you can hide and show, climb the sky in the spring breeze and dive into the deep sea in the autumn wind. It also brought clouds and rain, and later became a symbol of imperial power. Emperors of past dynasties used dragons as costumes, and their utensils were also decorated with dragons. Dragon was worshipped by Chinese ancestors as the ancestor god, and was generally called "dragon". People in China often call themselves "descendants of dragons".
