Yao, 56, leads four other villagers in using 10 mules to transport construction materials for building a mountain walkway. Working from 7 am to 6 pm, one mule can bring in a daily income of 300 yuan ($72) at most. Yao said they can eat simple food at a cost of 10 yuan a day, mostly noodles, but he usually spends 20 yuan for a mule’s food. (Photo/VCG)
