The dragon is a mythical creature in ancient myths and legends in East Asia such as China. It is often used to symbolize auspicious auspiciousness, and is one of the most representative traditional cultures of East Asian nations such as the Han nationality. Dragon culture such as the legend of the dragon is very rich. The most basic feature of the dragon's image is "nine resemblances", which nine animals are still in dispute. Legend has it that they can show and hide, can be fine and giant, and can be short and long. The vernal equinox reaches the sky, the autumn equinox is buried, and the wind and the rain are called, and these already developed images of the dragon in the late stage are more complicated than the original dragon.
