In Jishou City, Xiangxi Prefecture, Hunan Province, there is a bridge spanning the Dehang Grand Canyon of hundreds of metres-deep. It is the Aizhai Bridge, without any piers, like a "sky bridge" suspending in the air. And driving on the bridge is another story, with unfathomable gorges on either side and steaming clouds of fog and mist filling the sides whenever the clouds rise, as if entering the fairyland.
