Workers enjoy a meal in the cafeteria of a construction company building the Zhrong Rong Jasper Tower in Pudong, Shanghai, China. (From the book What I Eat: Around the World in 80 Diets.) In China, migrant laborers often live directly on the job-site grounds of big construction projects and work 12-hour shifts, seven days a week. Alcohol is only tolerated in the company cafeteria after dinner.
