AirBnB had tons and tons of listings in both places, all of which had specific instructions to tell the neighbors you were “a friend” and not staying there with AirBnB.
At the time, and possibly still so, AirBnB was not operating legally in those particular places, and I presume most of the country, but it’s such a good booking platform people used it anyways.
Long story short, I doubt China is not going to copy AirBnB, unless they can find a nice revenue share model with AirBnB the platform.
P.s. There is ripe opportunity to make apps that interface China to westerners traveling there. There was literally no way to hook into the QR payment system, get a Didi, navigate, or get good translations just 2 years ago. Good luck to those of you building products to help non Chinese people in China. You’ll do well.
