It depends really on the difference between what I expect, and what I want.
I wouldn't mind a demo where you begin in Shenhua's home, and are able to explore a bit, also take the path down over the bridge to Bailu Village, and be able to explore a bit more. But all story content is cut. Dialogue with NPCs is strictly a "Hello", or "How are you". Just to get a small feel for the game. Nothing spoilery or anything like that.
If there is story, then it would be involving the little girl we have seen so much of. As far as I know, the beginning of the games narrative involves her. But that's strictly it.
