In the past two decades, Li's efforts are the equivalent of climbing a total height of more than 1,800 kilometers.

He was awarded the title of Good Samaritan of China in 2012. The title honors people who perform extraordinarily in their work. China has been awarding grassroots heroes this title since 2008.

Compared with Li's dangerous job, Hu's work is demanding in a different way. He is the guardian of the time-honored pine tree, which has become a welcome symbol for guests. In 1981, authorities at the scenic spot set up a position to watch over the tree.
