'Width of cloth') is a type of guanmao (冠帽), a male traditional headgear generally made from a black fabric in China and Korea.

The fujin was later adopted in Joseon where it became known as bokgeon (Korean: 복건; Hanja: 幅巾) and became known as the 'hat of the Confucian scholars'.

[2] According to the Random Expatiations of Oju written by Yi Gyu-gyeong in the 18th century, "In the Chinese Han dynasty, many kings and the nobility admired the attire of scholars and considered wearing the bokgeon an elegant way of dressing.

Consequently, the bokgeon which used to be worn by people of humble origins, became part of scholarly attire by the end of the dynasty".

It continues to be worn in present-day Korea where baby boys wear bokgeon on their first birthday or on traditional holidays.
