Dong Xing'an, a 32-year-old man from Northwest China's Shaanxi province, collects seashells amid waves on Chengsi Island, Zhoushan, East China's Zhejiang province on Aug 17, 2011. Most of the seashell collectors are not locals, who are usually unwilling to take the dangerous job. Seashell collectors often work on remote islands, where they climb steep cliffs, and withstand a constantly changing climate. Some of them cannot even swim. But the monthly income - 2,000 yuan ($313.2) - is a big draw, as the collectors say it's much more than what they could earn in their hometowns. [Photo/Xinhua] 

Du Huaiming, a 35-year-old man from Northwest China's Shaanxi province, collects seashells amid waves on Chengsi Island, Zhoushan, East China's Zhejiang province on Aug 17, 2011. Du came to work in Zhoushan in 1999, because he is unable to work on boats due to serious seasickness. Du said the cost of living on the islands was high, and it's not good for his health to work fully exposed to the sun and sea. "I will go back home when I've saved enough money," he said.
