Mansu expanded across hills and valleys between mountain ridges. Apartments, low-rise housing and commerce were not completed through one plan at one date. Administrative Mansu 1–6 boundaries and the lived district differ. Slope creates views but also affects walking, drainage and access; distinguish designation, proposal, construction and occupancy.
Use dated official sources and check current hours, closures, tides, construction and transport. Separate production from sale, original traces from reconstruction, workplace from attraction, proposal from completion, and a single observation from a district-wide conclusion. Stay on public routes and obtain consent before photographing people or interiors.
