China actually wants people to visit them and spend money.

And although I don't agree with the CCP ideology the Shanghai subway is ridiculously impressive.

Remember most of the Chinese train infrastructure was built in the time since the Hyperloop.

I was not impressed when I was sent there on business trip, from what I remember their subways were not as big as in Beijing or other CN places and I hit there my head, obviously anything is better than HK/London. Normally I'm not claustrofobic, but in HK subway...
