Whats missing from those pics ....
On one trip there I watched the Chinese build 3 story concrete structures that were bamboo core with concrete stucco cladding. Nothing was cast or reinforced with steel. Shit was pretty scary from an engineering POV. Then again they would run electrical in buildings by twisting 2 light gauge wires together with no other insulation and staple em to the walls. And those fuckers love the dynamite the shit out of everything. the country structurally is a house of cards, expect it to fold over like Haiti in a big earthquake.
