How does Huangguoshan Waterfall flow to the small village above?

You mean Huangguoshu Waterfall, right?

Huangguoshu Waterfall is the largest waterfall in China and a rare scenic spot in Guizhou. It is a three-level waterfall formed by topographic drop and geological subsidence of river bed. As for the flow to the small village above? I haven't seen it. Maybe you mean the small village downstream. Because of the altitude, the river flows down from a height, giving people the feeling that the waterfall is naturally higher than the village.
