Does the theme support switching between English and Chinese？

I want to switch the whole site when switching languages, including articles, please ask if it is supported, or how to achieve it？

If I got it correctly, yes, it is possible.
Look at this article page. If you change the language to Portuguese, you'll be redirected to the same page translated to this language.

For each page, you'll need to create another file for each language you want to have.
