The photo shows a glass skywalk clinging to a cliff hundreds of meters high in southwest China's Chongqing Municipality. The distance between the outermost point of the skywalk and the cliff is 80 meters. Compare that to the 21 meters of the Colorado skywalk in United States. The Chongqing glass skywalk is more thrilling because of its length, transparent walkway, and "A" shaped tip design. (Photo/CFP)
