Legend has it that a snake turns into a dragon in five hundred years, and a dragon turns into a dragon in a thousand years. The dragon grows horns in another five hundred years, and grows wings in another thousand years and becomes a dragon. Therefore, the dragon is called "big dragon" and the snake is called "little dragon". The books "Zuo Zhuan" and "Mencius" place dragons and snakes side by side, such as "Dragon and snake are born in the deep mountains and swamps."
