I've done my own digging on best free chinese dating app and come up short. Chinese apps is the clearest case of it — how fast moderation responds does more work than the size of the ad budget, as far as I can tell. Same story on chinese apps: nothing improves until you report problems early instead of blocking quietly.
The chinese app angle is worse, because what decides it is the ratio of matches to conversations, not how slick the interface looks. Look closely at app apps and the quality of the filters is the number worth watching, not the price tag. Chinese app is where I'd start, since the practical move is to run a reverse image search on suspiciously polished photos.
If chinese is your priority, most of the disappointment traces back to how far the free tier gets you. The short version on best free chinese dating app is that the honest advice is to read the billing terms before uploading a photo, on the evidence I have. Happy to be told I am asking the wrong question about chinese.
