The Book of Songs is the earliest collection of poems in China, and its chapter Xiaoya contains "What is a good dream? Xiong Weiwei, Wei Biwei snake ... Xiong Weiwei, the auspicious of men, Wei Biwei snake, the auspicious of women. " Bao Puzi: "There are dragons of nature and snakes." Zheng Xuan's Note on the Biography of the Hongwu Fanxing: "Snakes, dragons and the like." Strange Tales: "Cricket turns into a dumpling in five hundred years, and a dumpling turns into a dragon in a thousand years."
Moreover, in ancient times, the characters or gods in the records were sometimes called "snake bodies" and sometimes "dragon bodies". For example, we all know that Nu Wa is a snake face, Xuanyuan Huangdi said it was a snake face in Shan Hai Jing and a dragon head in Shuo Bo.
Moreover, as we all know, the dragon was invented by our ancients, and when the snake shaped this animal, it contributed its scaly body to the dragon. Its soft and twisted body was also endowed with the characteristics of invisibility, movement, good and evil. It can be said that it makes sense to call a snake a little dragon.
