Students play between classes at an elementary school in the impoverished Cuihua township, Luquan Yi and Miao autonomous county, Southwest China's Yunnan province, June 20, 2011. News came to light that malnutrition was widespread among students in the poor county after an online post revealed that students at the elementary school can afford only two meals a day, mainly potatoes. One child said his biggest wish was to eat a watermelon, the post said. [Photo/Xinhua]
