Sadly I don't have any good way of adding Chinese language in the game, other than recurring to an MTL and its issues.
I plan on adding more languages to the game once it receives enough support, but there's currently no way for me to add Chinese language by myself alone.
I have 1 suggestion as to adding more languages instead of using google translate which has no context based translating try using DeepL but i forgot whether or not it has Mandarin or its dialects and better let the fans do it for you
