The water reservoir 水库
The temple Tangshan Si 唐山寺 was built in this valley in Tang Dynasty (618-907), which was before the year 907. Zhou Fu rebuilt it in 1880; the mountain is named Zhou. The Zhou Ancestral Hall 周氏宗祠 moved up when the valley became a reservoir. The foundation of the temple is still visible.
I never could have taken enough photos of water. And I was thinking, yes, if this place is good for swimming.
Above the small cliff is the Zhou Ancestral Hall 周氏宗祠.
