@everyone here is the first test client of pbo with Chinese language support. https://mega.nz/file/O5NziYQL#Z56J6ZGEo_2f-Aw_iLq2KkGu4322IiiBYHKerzh8LOk
To change language, just use the settings and change the language to Chinese.
This is just for testing and you might encounter some client side bugs. Please report them in bug-reports.
