Ancient walk-ways are reconstructed into the mountain cliffs, its planks made of glass.
It will become a special adventure, to walk along miles of ancient paths, once created by the military of the Han dynasty. Cliffs were drilled with post-holes, and planks were used to create the miles of routes. On many spots, as you can see by enlarging this photo, the planks are made of a special glass. As you are walking, it is as if walking on air, above the torrents of water.
