Hey!
There's two "shopkeeper/quest giver" npcs, a bat, a skeleton and a cyclops with basic animations. They are all featured in the screenshots on the project page! They're meant to be "examples", as the tileset is really about level/dungeon/location creation; the tileset being 8x8 pixels, it would be very easy to create or import additional NPC sprites. I have also tried working with 16x16 sprites for both the protagonist and the NPCs and it worked pretty good.
The tileset comes with a basic Latin font (there's a list of the included characters/symbols); I guess if you have an appropriately sized Chinese character set, it would work fine with the tileset.
Hope this answers your questions!
