I have been to China many times and to Tianjin 3 or 4 times. I ate at my first 3 story McDonald's there.
Whether it is engineering projects, construction or even retail business, everything is massive and you just add a few more zeros to your initial observations. Construction is very often on a 24/7 basis and taller buildings may be occupied on lower levels before being topped off. I have given a few seminars and found the engineers are ravenous and well equipped to learn.
It even out-strips India in the desire and talents for design and construction, especially considering what else that can be required.
With the huge facilities and concentrations of industries and population, the disasters can have huge numbers associated with them.
