Hello,
The Chinese version is fan made, so we don't have control over it, but to my knowledge, the translation is 100% complete.
If it's not up to date on your device, you can always download the .json file from here: "https://drive.google.com/file/d/1ZFOR8E-XGDJKI0uZnfmWEtw0g4WfpIDt/view?usp=drive..." and install it ingame using the "+" button in the options menu.
