[2] Portraits and literature of Kim Seon, Kwon Seop, and Nam Do-jin confirmed that "Hakchangui" was also used as a clothing symbolizing scholars who escaped from power and lived a life of the world.

This type of clothing can be traced to the Joseon dynasty, and were used by scholars and officials, as shown in various portraits like the one that shows General Jang Man.

[4] Hakchang, called the clothes of the gods, was worn by virtuous scholars, wrapped around the edges, and tied up with a vast royal band (sejo-dae 세조대).

In addition to the fact that the same type of clothing in the 18th century was hung up and down with a ring bead on the impactful part without covering the collar.

The formality of opening the school uniform is to use a button or a pole,[3] the Hakchang and Hakchangui borrowed from China in the first half of the 17th century can be seen in the same form of clothing as that of Zhuge Liang.

It was worn mainly by scholars who had exchanges with China, and it is gradually spreading around the students who follow the teachings of the teacher who wore the school uniform or those who like antique things.
