Rural migrant workers sleep near Zhengzhou Railway Station, Central China's Henan province on Feb 7, 2012. Henan is one of the main labor sources in China. After the Lantern Festival on Feb 6, swarms of migrant job hunters flocked to Zhengzhou city. Many of them are over 40 years old, not well-educated and without professional skills, making it hard to find a job. During their job search, some sleep on the streets to save money. [Photo/CFP]
