Actually building in Shangai is quite difficult due to the nature of the soil/ground..
Considering the rate of growth and the amount of projects taking place one building is acceptable. Landslides and miscalculations in the physiology of the ground you are building happens all over the world.
The weird thing is that the building fell on its side and still is more or less intact. I would say that this is amazing and in my eyes show a good cement and static analysis involved in the constraction of the building!
"Lo there do I see my father.
Lo there do I see my mother.
Lo there do I see my brothers and my sisters.
Lo there do I see the line of my people back to the beginning.
Lo they do call to me
they bid me take my place among them in the Halls of Valhalla,
where the brave may live forever"
