PPT turned into video, showing high-altitude footpath being built in 2011 on the side of a vertical wall on Mount Shifou in Hunan Province. There must be some kind of crazy steep tourism movement in Hunan, judging from the glass-bottomed walkway built on the edge of the province’s Tianmen Mountain. This is one of the things I love about Chinese tourism: it’s sheer fun and awe with less attention paid to dangerous liabilities. Probably this will all change in the next few decades, but for now, you can do things in wild places that you would never be allowed to do in the U.S. (thanks Kim and Sean!)
