Open Data Kit: open source, runs offline, lots of customisation if you really want to get into it. You can pay or host yourself. https://getodk.org/

I assume running offlline can be useful as China may block some websites.

You can download and install the APK manually (Google Play is blocked in China)

Kobotoolbox is also worth a look in my opinion, they share a lot of similarities

You can use Psytoolkit, it can also be run offline, it suports Chinese (traditional) and Chinese (simplified) languages.

You can run surveys but also reaction time experiments. The community is very welcoming and helpful.
