Some questions about Chinese translation

Hello, I had some problems about translation into Chinese .
In the beginning, I put the folder named “Chinese” on the path “\common\Democracy 4\translations”, and it works normally.But when I trying to make a mod for workshop, some fields are missing or displayed in English. Im sure I put the folder on the right path(mods/chinese_translation/translations/Chinese).How to solve this problem?
In addition, I found that it works only when the file name is called ‘Chinese’,otherwise Mistaken Code will occur(The words become square and messy).
