This is anecdotal, but I'm sure anyone who has traveled around China can confirm: housing is not normal there. On one 5 hour high speed train ride between Shanghai and Beijing, I saw no less than 2,000 apartment high rises scattered throughout the countryside, most of which, clearly didn't have tenants - no cars, no laundry hanging out windows, nothing. These are only the apartments I could see from the train too! At some points there were hundreds of identical, 20+ story apartments scattered all over the horizon with very little activity around them. I hadn't seen anything like it in my life. The strangest things I saw were 20+ story highrises just chilling in the middle of crops - no roads leading to them, just standalone in a big field of some crop.
At the time I was weirded out, and upon further research it seemed like there was and is something more systemic going on that we can't wrap our heads around.
I know this is very anecdotal, but I was hoping to get some comments from others that have travelled around China to see if they have noticed similar things.
