The difference between Fengtou Xiapi and Fengtou Bi Xia

There is no difference between a crown robe and a crown robe.

Under-crown iron and under-crown skin refer to the same traditional headdress for women, which is made of red silk and presents the shape of wearing on the head. It is a part worn by women at weddings or other important occasions, symbolizing happiness and beauty. In the ancient court, the queen or imperial concubine also wore this headdress.
