Mount Hua (华山/華山) is one of China's "five great mountains" and is well known for its precipitous cliffs and dangerous plank paths. The Changkong plank path (长空栈道/長空棧道) is a famous tourist spot which literally means "skyway". 20 years ago when there was no security rope provided for tourists, many people died climing it. Now with security ropes it is much safer.More information: en.wikipedia.org/wiki/Mount_Hua
