Walking to 2 miles from Xianyu entrance, there is a slant-ridge blocking the way, the broad road are pushed into a thin ribbon of a trail. This is the Xianyu Lingxu Grand canyon walkway of Mount Hua. The cliff stands vertically with more than 100-metre-high and 3 to 4-metre-width, forming One-Line-Sky marvelous spectacle. There is a folklore, this mountain is surrounded by auspicious cloud, a place that the visiting celestial beings stopped and had a break. So it works making a wish here. Pebbles were stacked up along the both sides of road when many people came to worship the gods. Walkway was started to build on March, 2008, and completed on August. Builders risked their lives to work hanging in the air, building the beautiful wonder with their wisdom, courage and perspiration, lifting a veil of valley mystery.
