Tinder in China (tier 1 city) is 50% local 50 % expat
The locals all mention they just wanna meet more people and make new friends ( they obviously know it's a hook up app) since they are soo lonely working at their boring jobs, but obviously you can game then too, just gotta be more subtle in your approach. China is still quite a conservative country and the hooking up openly on apps (I have an impression) is not too well looked on by the general public, so if you get past that, your success rate goes up. (The other way is to screen for more dtf chicks, but wechat is better for that.
