Wangjin is a kind of traditional headgear worn by adult men in the Chinese Ming Dynasty.

One day, the Hongwu Emperor of the Ming dynasty wore common clothes to visit the folk and he saw a Taoist priest wearing wangjin on top of his head.

Wang Bu, a man from the Qing dynasty, once introduced the wangjin as something that looks like a fishing net.

In the Wanli period of the Ming dynasty, people began to use fallen hair and horsehair instead of silk to make wangjin.

Nowadays, historians and the people interested in Chinese history research ancient books and historical relics to restore various forms of the wangjin.
