Zishan Mountain, (also known as Sanping Mountain), is located about 50k away from Zhangzhou City in South Fujian, (thats part of China if you didn't know). The mountain is home to Sanping Temple and a very pretty waterfall.
This has become quite a tourist spot in recent years, due to the scenery, and the waterfall. But unfortunately no one ever tries to go over this waterfall in a barrel.
