Muhoga Chongchakji (settlement without permission) is the legal, technical term city planners use, who find it more convenient to look upon poor districts of Seoul as illegal rather than as traditional or alternative housing.

Taldongne and Sandongne (moon village) and (mountain village) are more poetic terms for the informal settlements which came into the city with the flood of rural migrants in the 1960s. These terms refer to the location of Seoul’s poor settlements, many of which were built on the steep hill-slopes and undevelopable hilltops throughout the city, where the moon was indeed a bit closer.
