Confinement nurses, or yuesao, head to Shenzhen city, an industrial hub in South China's Guangdong province, after finishing their training in Xiangyang, Central China's Hubei province, April 25, 2012. Nearly 30 confinement nurses, who performed well during the free training by Xiangyang's labor union, were asked by domestic service agents in Shenzhen to provide service for homes in that city, where the demand for such nurses is high. To meet the urgent demand, Xiangyang's labor union worked with agents in Shenzhen to train the nurses. China is expected to see a baby boom in 2012, which is the Year of the Dragon and seen as an auspicious zodiac sign by many Chinese parents.[Photo/CFP]
