What is the name of the hat worn by men in the Tang Dynasty?

The hat worn by men in the Tang Dynasty was called a turban. Turban is the most common "hat" worn by men in ancient China, especially in the Tang Dynasty. Turban was originally a four-legged turban used by men in ancient times to wrap their hair, also known as a folded scarf. When folding and wrapping the head, each person's folding skills varied, so the folded turban was shaped differently. During the Sui Dynasty, Niu Hong, the Minister of Rites, wrote to the court suggesting that a skeleton be set up inside the turban and placed over the head to facilitate the folding of a uniformly shaped turban, which was later developed into a turban with a skeleton. Emperor Li Shimin of the Tang Dynasty liked to wear a turban when he wore his regular clothes. Soon, people began to follow the emperor's example, and the turban became the most common "hat" in the Tang Dynasty. There are many types of turban, such as the soft-footed turban in the Tang Dynasty period; and the hard-footed turban in the mid-to-late Tang Dynasty.
