Children climb up a walkway along the edge of a cliff on Jinzi Mountain in Lianshan Zhuang and Yao autonomous county, South China's Guangdong province, on Sunday. Four boys and two girls aged from four to 11 years old took a one-hour journey on mountain roads, including the walkway that is on a steep, 500-meter-long slope, while five fathers held bamboo strips to steer them ahead without taking a break.
