The question is what medium you used to install initially what was your Mageia 8 install before ...

What I want is to have multiple language ...
That's why I've asked. localedrake is used to select the main language for the system.
Also you didn't really answer what having multiple languages does actually mean for you.
Do you only want to switch some particular program between french or chinese? Or do you want to run your whole desktop session in one of those languages?
Do you need only e.g. man pages or handbooks in those languages? Some more information what you actually want would be helpful.
In general you need to install the locales-xx package for the languages you want. ( you probably want locales-fr and locales-zh )
Based on those and/or what you have in /etc/rpm/macros for the "%install langs" macro, the respective language files are installed when you install any package which contains language-specific files like man pages, documentation or translations.
