A gong is one of the percussion instruments, also called gilt or simply gold. It is a musical instrument widely used since ancient China. It was imported from the Ming Dynasty of China during the reign of King Gongmin of Goryeo (1351-1374), and was widely used in Jongmyoak, Muak, Beopak and Nongak.
Making gongs is made by beating brass in a group of Daejeong, Gajidaejeong, front-machin, Jeonmachikun, Senmachikun and Pulmuone on a night of the agricultural cold from November of the lunar calendar to February of the following year. The production process is brass-greening, elongating, embossing, potting, cheapening, flirting, snuffing, puffing, eggplanting, and crying, especially in the end, crying-gathering, which coordinates the sound of the gong, requires highly skilled skills.
In the area of Anui-myeon, Seosang-myeon, and Seohae-myeon, Hamyang-gun, the old Anui-hyeon area, there was a time when the production technology was the best in the country due to the fact that it was an organic percussion workshop. Until the 1960s, the function of the inner area gong was inherited, but there were one in Ggotburi Village in Seosang-myeon and one in Songgye Village in Seohae-myeon, and Lee Yong-gu, the holder of the function, is a member of the Ggotburi family.
Currently, Jingjiang Yi Yong-gu is making gongs with modernized manufacturing techniques, while setting up traditional gongs next to them and producing gongs by order, continuing the traditional inner gongs. The traditional inner gong is characterized by its loud, grand sound and long wavelength.
