Could you specify that? Are the characters not working? Since none of us is chinese it is not that easy to really test that.
Could you please send a link so that we could see how it looks like?
Or do you mean translating? Internationalization is in the works for 1.2. You could vote for that feature in our poll on www.zenphoto.org/category/News
daohe, is everything working for you?
just download zenphoto nightly version (at http://www.zenphoto.org/files/nightly/) and then install it like you would install the 'normal' version. I'm using one, and it works for me.
had the same problem initially too, searched the forums and found this discussion (http://www.zenphoto.org/support/topic.php?id=1949&replies=3), if that's any help to the developers. :) chinese characters were displayed correctly before v1.3.3, somehow it went wonky after the upgrade.
