Seen at Sudoguksan (Water Works Hill) Museum of Housing and Living, just east of downtown Incheon. Water Works Hill hosted a shantytown, made up of displaced rural peasants and Northern refugees, which lasted through the industrialization years until being gentrified in 1996; there is a museum dedicated to life in the shantytown, a valuable resource to remember a bygone era.

Rat infestation was a common problem in shantytowns, due to a large number of people in a confined area (read: more food scraps) and the presence of empty places for rats to live and breed (such as the heating pipes). The Ministry of Agriculture and Fishing announces that rat poison are to be placed around the neighborhood on December 13th at 5 in the afternoon.
