If they eat up their food, students can collect coupons (优惠券) and exchange them for small gifts, such as books, magazines, mobile phone covers and hand warmers.

“It’s been such a surprise,” said Liang Zhaoyun, a student at a university in Shanghai, “It has given us one more motivation to finish our food.”

The action is part of a national “eat-up” campaign (行动) which is organized by students to deal with food waste on campuses (校园).

Why only on campuses? You might ask. Because according to a report by Xinhua News Agency, students waste twice as much food as the national average (平均).

The campaign on campus food waste is receiving attention across the country.

“The aim of the campaign is not only to encourage students to finish their food. We hope it can also encourage students to choose a more environment —friendly and healthy lifestyle,” said Tao Siliang, Secretary of the Youth League Committee at Shanghai University.

Some school food doesn’t taste delicious, so students do not like to finish it all. Some schools have taken notice of this and they are taking actions to improve it.

“I’m glad that we’ve reduced food waste since the “eat-up” campaign began. But if we call on students to waste less food, we should also improve the service and food quality on campuses.” said Tao.
