To be honest, I'm currently too preoccupied to worry about localizing Sihai's Legacy to other languages (although, Chinese would be my first pick). I'm not sure I could officially and actively support a translation of Sihai. Unofficially, however, if some fan were willing to go out of their way on their own to make a translation of the free to play, itch.io build and post it for Chinese audiences, I wouldn't mind so long as proper credit and references are given due.
Sorry if that isn't as helpful an answer as you were hoping for! ๐โโ๏ธ
