Before the Qing Dynasty, soldiers' hats were made of iron, but the hats of soldiers in the Qing Dynasty were not made of iron! What material is it made of? That soldier hat looks like an awl.

A "hat" is worn in summer and is called a cool hat. The strips are woven into a skeleton, and the outer cover is graceful.

"Bowl hat" is worn in winter, which is called a warm hat, but it is not a cotton hat. Its texture is mostly leather, woolen cloth, satin and so on.

It's no use. I combed my hair, and my forehead is light, which is used to cover the sun, haha.
