At a construction site in Xi'an, northwest China's Shannxi province, a group of carpenters work busily on the 26-storey-high scaffold. Their work is to put up and dismantle the concrete formworks. Sometimes they will make frameworks in special shapes, such as cylinder or arc. These carpenters are handsomely paid, but their work is laborious. In summer, in order to work in relatively cool weather, they begin to work at 3 am and stop until the moon rises. However, they are happy and often make jokes to each other while working. Those hardworking people are beautiful. [Photo/people.com.cn]
