The small village of Da Sy, located in Kien Hung Commune, Ha Dong Town, Hanoi, has a long history of producing skilled craftsmen. During the wars in Vietnam, the village was a major supplier of weapons to the Vietnamese military. However, after 40 years of peace in Vietnam, the people of Da Sy returned to their traditional occupations, producing agricultural implements such as ploughs, rakes, and machinery parts, as well as kitchen implements.
