XIAOZHU It's very simple. After setting up Flarum, just use the `webview` tag and embed the corresponding URL. Development takes about 10 minutes, then submit for WeChat review. If your site has substantial content, the probability of passing the review will increase.
Domestic forums tend to have stricter requirements. It's important to ensure you have the necessary qualifications, including standard ICP registration and police registration, as well as relevant materials related to information security. You should also pay attention to internal content safety. For more details on the new version of the "Commenting Regulations," please see:https://bbs.hamzone.cn/d/87
The Chinese community plugin for Flarum that you mentioned, I have tried it out. The development is not yet very complete, and it's not as good as using a web page within a webpage. However, the user experience might be slightly worse. Currently, it's still usable.
Regarding the English-language Flarum community, someone has developed a mobile version, but it was discontinued after that.
