> Where and who did you get this idea from? Speculation in China makes speculation in the USA look like child’s play.

This information is so out of date it borders on misinformation. China's real estate market "crashed" at least 5 years ago at this point. And it didn't just crash in the same way that, say, the Toronto condo market has crashed. It crashed because the government burst the bubble, deliberately, to make housing a priority not an investment. Put another way, like I said above, housing people was made a priority over investor returns.

> HSR isn’t used for commuting in China

China's HSR now has over 4 billion passenger movements a year [1]. It's largely an alternative to short=to-medium distance air travel eg Beijing to Shanghai is ~1200km, roughly equivalent to Chicago to NYC. What's commuting got to do with it? Are you comparing to Japan where people might live 2 hours commute away from work for various reasons?
