Qi Haoran, a Junior 1 student, was quite busy over the past winter vacation - and not just with homework.Qi, together with 10 other classmates made a volunteer group to call on people to join the Clean Your Plate Campaign (""). The 11 students went to many restaurants and told people the importance of saving food."Excuse me, do you know that 950 million people around the world still haven't got enough to eat? Please don't waste food." They would say this kind of thing hundreds of times every day. The Clean Your Plate Campaign began on the Internet in January.It calls on people to reduce food waste. China in these years had serious problems with wasted food.CCTV reported in January that the food Chinese people waste every year is enough to feed 200 million people for a year. Chinese people are well known for being hospitable   and generous .Many even feel that they lose face if their guests have eaten all the food. Luckily, the campaign has got the support of many.In a restaurant in Xinjiang, the owner give the guests who have eaten all that they ordered a sticker  .People can enjoy a free meal when they have 10 stickers.More than 750 restaurants in Beijing have begun to offer smaller dishes and encourage their guests to take leftovers   home. To reduce food waste is a big task, and it needs time.It's important that everyone does their bit, just like Qi.Did you finish your meals today? ,A, B, C, D.
