During the Spring Festival, people often prefer to try new things and to enjoy themselves a lot after one year’s hard work, but it has increased some unnecessary consumptions (消费) . The “clear your plate” campaign (活动) started before the New Year, and runs through the two festivals. People began to think about their consumption patterns (模式), “to clear your plate” has become a more and more welcome “New Year Style”. Reporters have learned from many restaurants in Lhasa city that during the New Year. Customers pay more attention to family get-together, and a lot of families will ask them to pack leftovers (剩菜) home after meals. According to Mr. Zhou, a canteen manager at Central South University, said that students produce over 12 barrels (桶) of leftovers every day — each barrel stands at one meter in height. According to Xinhua News Agency, the food wasted by Chinese people equates to (相当于) about 50 million tons of grain every year, or 10 percent of the country’s total annual grain production. Come on, dear friends. Let’s start with ourselves. Let’s stop throwing away food. Information Card
