What are the shapes of women's bun in Han Dynasty?

Women in the Han dynasty used to comb their hair into a bun, which was called a woman wrapped in a special headscarf. Ordinary women comb their hair flat, while aristocratic women like to tie a high bun, which is woven with metal wires in circles. Steamed buns come in many shapes. According to historical records, there are more than ten kinds of steamed buns, such as Xiaoma Steamed Bun, Yaotai Steamed Bun, Yingchun Steamed Bun, Wangxian Jiuhuan Steamed Bun and Fenxi Steamed Bun. The bun is decorated with hairpin, one foot long, and the end is decorated with Watson, also known as Watson. It is often a phoenix inlaid with jade ornaments, with colorful beads hanging down, which shakes with the footsteps when walking, so it is called walking.
