A man works in a salt field in the Daishan County of east China's Zhejiang Province, July 16, 2013. Daishan is the largest salt-production county in Zhejiang. Workers usually work long hours in the sun to evaporate brine during the golden salt-producing period from July to September, the hottest three months in summer. Due to the hard work and low income, fewer young men would like to be engaged in this occupation in recent years. Therefore, the salt field is likely to vanish in the near future. [Photo/Xinhua]
