Workers are unloading bags of construction cement from a train at a railway station in Fuzhou, capital city of the eastern province of Fujian, on the night of April 26. Most of them have lung problems though they all wear masks while working to prevent the excessive inhalation of cement dust. On their best days, they may be able to deliver 800 bags of cement a day and earn 344 yuan ($54.73), half of which will be used to pay for their meal fare. Majority of the cement used to construct buildings in Fuzhou is unloaded by them. [Photo/CFP]
