A two-year-old boy, the son of a vendor, sleeps next to oil paintings at a gallery at Dafen Oil Painting Village in Shenzhen, south China's Guangdong province April 26, 2011. Dafen village, a suburb in Shenzhen, is believed to be the largest mass producer of oil paintings in the world. Artists here manufacture some 60 percent of the total global trade volume. Thousands of artists and dealers rent shops or exterior walls on buildings to display and sell oil paintings, but they will soon need to find other places as the local government has pledged to ban the practice in an effort to brush up its image before the upcoming Universiade.[Photo/Agencies]
