[iChenLei]

Code change checklist

• Added/updated unit tests
• Updated /docs. For new functionality, at least API.md should be updated
• Verified that there is no significant performance drop (npm run perf)

Target

Seeking more ranslation volunteers, when we finish the translation work, we can edit the config like this:

- { href: "https://zh.mobx.js.org", label: "中文(寻求翻译)" },
+ { href: "https://zh.mobx.js.org", label: "中文" },

寻求翻译 = seeking translation

Easy to jump v5/v4/v3 chinese docs
