You don’t pay property tax in China. That’s one of the greatest things as a home owner there. As this country has a young government of only 58 years history, it has been experiencing a lot of revolutions since day one (bad or good). Policies can change. I read news that in their congress meeting(People’s representation assembly), some people have already proposed to make land private property for several times, but those proposals did not pass yet. It will pass one day.
