China has its own "spidermen" in Huangshan, Anhui province, whose mission is not to save the world, but to collect trash from mountaintops or pick up cellphones dropped by travelers.

Li Peisheng, 51, is one of the 18 spidermen who rappel down Huangshan Mountain, one of China's top tourism destinations, to keep the UNESCO World Heritage Site clean.

Famous for peculiarly-shaped peaks, pine trees and views of clouds, the mountain range includes three of the scenic area's tallest and best-known peaks — Lotus Peak (1,864 meters), Bright Peak (1,860 meters) and Capital of Heaven Peak (1,830 meters).
