Hanjijang refers to a craftsman skilled in the art of making traditional paper, hanji, from the bark of mulberry (Broussonetia kazinoki) trees and mulberry paste. Making hanji requires great skill and extensive experience. The mulberry bark has to be collected, steamed, boiled, dried, peeled, boiled again, beaten, mixed, strained, and dried; 99 processes are said to be required to get the paper in one’s hands, so the final process was also called baekji, meaning “one hundred paper.” Korean hanji was so famous back in the Goryeo Dynasty that the Chinese called the best-quality paper Goryeoji (literally meaning “Goryeo Paper”). Sun Mu from the Song Dynasty of China lavished Goryeo paper with praises in his book Jilin leishi (Things on Korea), saying that it was white and glossy and lovely. In the Joseon Dynasty, from the time of King Taejong, the state began to oversee paper production, establishing the office called Jojiseo (Paper Manufactory). In modern times, however, the change in architectural styles and housing environment and the import of paper have led to the virtual disappearance of traditional hanji. Today, because of high production costs, hanji is made with pulp imported from Southeast Asia rather than mulberry bark. To keep the art of hanji alive and pass it on to the next generation, the Cultural Heritage Administration has designated hanji making an Important Intangible Cultural Heritage.

Gwanghwamun is the main gate to the south of Gyeongbokgung Palace. It means "the great virtue of wages reflects the whole country."

Built in 1395, a pair of hatch sculptures are located on both sides of Gwanghwamun, a two-story pavilion. There are three Hongyemun (Archimun) on the stone pillars of Gwanghwamun. The middle door was the king's, and the other left and right doors were the servants' doors.

On the ceiling of the gate in the middle of Gwanghwamun, there is an abacus. Gwanghwamun was destroyed twice by the Korean War, and on August 15, 2010, some restoration works were completed except for Woldae and Haitai.

In modern times, the name "Gwanghwamun" itself is not only used as a castle gate, but also as a common name for Sejong-ro in Beopjeong-dong, including Sejong-daero and Gwanghwamun Square.

In fact, the Sejong-daero intersection, where Sejong-daero, Jongno-gu and Saemunan-ro intersect, is about 600 to 700 meters away from Gwanghwamun, but it is often called "Gwanghwamun intersection (intersection)".

The Uijeongbu and Yukjo government offices were established to perform key administrative functions since the Joseon Dynasty, and this area is one of the places where Seoul's history is implied along with Sungnyemun Gate.

In other words, it is one of the landmarks in Seoul.
