Huang knocks a rock to determine whether it is safe to grasp during climbing on a cliff. With bare hands, no safety ropes and loosely laced canvas sneakers on his feet, Huang Xiaobao, a 52-year-old villager clambers up the sheer rock face of cliffs along Getu River in Southwest China's Guizhou province. Huang, a man with one of his legs affect by polio, started to learn skills of free climbing from his father when he was only 12 years old. In the past 40 years, the man with strong arms always climbs 100 meters in search of swallow droppings to fertilize local terraced fields. (Photo: China News Service/Ning Jian)
