While is is true that the requirements are nothing new, what struck me the most was the stark difference in application.
The application of these design requirements went from token box ticking exercises to extremely serious in the last few years especially, and from purely anecdotal observations, it looks to me like the preparations are systematic across the country rather than focused to specific cities like Beijing previously.
A lot of this is hard to measure and observe, as few foreigners will be going to the underground parking garages of random Chinese residential blocks, and since I was travelling with a foreign passport holder, it was actually eye opening to see how few hotels would accept foreign guests and how defensive the staff got at the mere approach of a foreigner (we just wanted to get a coffee from the restaurant of a hotel and were turned away).
It all left a strong mark on me that from the admittedly small sampling I personally witnessed, I was deeply impressed with the application of the design requirements. These newer shelters are built like they are actually meant to be used, and are not limited to just the city centre. If you find such shelters in 3rd line cities and in flats well outside of the city centre, that’s pretty persuasive evidence to me that the application is nation wide.
