Each cabinet was a craftsman who engraved letters, and each piece was mainly composed of woodblocks, wood type, pyeonaek, and other wooden boards for printing, and was also used for wooden furniture such as hangers and bookshelves.

However, as these traditional individual cultures have been rapidly disappearing due to the development of photography and printing materials in recent years, they were designated as intangible cultural assets for the preservation and succession of traditional technologies.

Lee Chang-seok, a craftsman who has been working on his own since 1978, has not only restored the entire woodblocks of "Wolinsukbo," "Hunminjeongeum," "Hunminjeongum," and "Jipwangseongseo," but also produced many woodblocks.

In addition, through thorough analysis and historical research, many wooden types such as "Donggukjeongun" were restored, and each of the traditional functions was recognized as a holder to preserve and transfer his excellent production functions.
