Cleaner Guo Youshun clears off garbage on a cliff at the Red-stone Gorge of Yuntai Mountain scenic spot in Jiaozuo, Central China's Henan province, April 28, 2017. Like "Spidermen", cleaners here have to climb up and down the mountain to pick up rubbish left by tourists. Helped by two security staff members, a "Spiderman" has his waist tied with a rope and collects trash with tongs or broom. Even a small piece of paper will be picked up. These "Spidermen" are getting busier lately as a tourist peak comes.(Photo/Xinhua)
