More than a thousand years ago, the Tang Dynasty was the heyday of China's ancient society. The colorful costume culture in Tang Dynasty is an important part of Tang civilization. Clothing in the Tang Dynasty was hierarchical and varied. There are 13 kinds of coronation clothes for emperors to attend major events. The crown is hung six times before and after, and the upper body is dark blue and the lower body is red with sauce, which is called Xuanyi Xunshang. This coronation suit is embroidered with 12 dragon pictures of the sun, moon, stars and mountains, with the sun and moon embroidered on both shoulders and the stars embroidered on the back, in response to the saying that "the son of heaven shoulders the sun and moon and bears seven stars". The shoes worn by the emperor are called platform shoes.
