Liu Jichen, a student from Tsinghua University, has developed a WeChat mini-program (微信小程序) called "Clear Plate". After a meal, users can use the mini-program and take a photo of their empty plates. Once the picture is checked by AI (人工智能), users can collect points and use them to buy gifts or meals for children in poor areas.
Liu said, "4. 它是一个解决食物浪费问题的好办法。" He set up a team to work on this mini-program. In order to improve (提高) it, the team spent half a year collecting over 100,000 photos in university restaurants. 5. In 2018, the mini-program was put into use. Soon, it became one of the most popular mini programs in the university.
At the same time, Liu and his team started the "Clear Your Plate" project in November in his third year of university. Almost 1.6 million (百万) college students joined the project and food waste was reduced (减少) by 862 tons. "Through the project, we hope to encourage everyone to take action against food waste," he said.
Thanks to Liu Jichen's great efforts (努力), the students can save a lot of food.
