I can recommend you the titanium TiGr lock. I got the mini one in the US, don’t know if you can get it here in China though. Be aware that it’s not cheap. https://tigrlock.com/ Or you can add at what you find here a cheap GPS tracker
Damn, I didn’t know that lock existed until earlier this week when I bought a used bike here that came with that lock… only to find out after getting the bike that the lock actually wasn’t available 🙁 Looks like an amazing lock, though.
