Gudeok Mangkeuttajigi is a traditional folk song that includes the work of building a fence or pillar using a tool called Mangkeul to build a large building or house, and the song of labor (mangkeum) sung by a singer in the process.

Manggae are made by tying four to five handles or strings of wide stones or shits, and Busan uses wide stones, unlike other places. When the workers pull the rope up and let it go, the manga hits the ground and becomes more and more solid. As such, ironing the ground with a manga to strengthen the site is called a manga, and the sound called to relieve the fatigue of labor and to keep in step with the efficiency of work is called a manga.

The Gudeok Mangkeot Dajigi, which runs around Daesin-dong, Seo-gu, is of great folk value as it still has the old image of the work process of ironing the site with mangkae and mangkae, which are tools for ironing the site in traditional architecture, and the sound of mangkkeum is also valuable as a labor song in Busan.
