I doubt this FT in PRC poster is Turnoi. The problem is that you are whining about something that you have zero control over.
On top of that I feel that you have an entitlement mentality due to having a Chinese wife and kids with her.

You will not be treated differently to any other foreigner in China and you should not be.

Move to a place where the law is much less restrictive than China if you want to be more happy and content. Otherwise just accept what you can't change.
