"Huangshan scenic area received about 800,000 tourist visits annually about 20 years ago. At that time, we used to rappel seven to eight times a day or even 10 times to pick up trash. In recent years, tourist visits have reached about 4.5 million per year, but we rappel four or five times a day, and seven or eight times a day during peak tourist seasons, which means that the public has increased its awareness of protecting the environment," he said.

"Some young adults use plastic bags to collect their own trash and take it away with them. I remember a mother telling her child not to litter after seeing us rappel to pick up trash. The job is meaningful, and I'm very happy to see more people become aware of protecting Huangshan.

"We safeguard the mountains and rivers to safeguard the future for the younger generations. I will continue to protect the beauty and cleanness of Huangshan and let more travelers experience its charming natural views," he said.
