Sorry to have found that with 1.1.3beta3, the Chinese locale is still broken~This review is for a previous version of the add-on (1.1.2). This user has 2 previous reviews of this add-on.
I'm sorry but I don't speak Chinese so I can't really test to verify how it should work.
Another user stated that he edited the xpi and then it worked, if someone can provide us such updated chinese files we can release a new version with the fix
