China throws（扔）away enough food to feed about 5, 000, 000 people every year. President Xi calls on Chinese people to stop wasting their food and try to change the bad habit. It’s called Operation Empty Plate（光盘行动）.
“We’re going to prepare plates of two different sizes for people. That way, they can choose the one they need.” A restaurant owner said.
Some eaters are known as “big eaters”. Today it is not easy for you to find them. When you search for “big eaters” online, you can watch a short video. The video tells people not to waste food.
Now, schools around the country are also teaching children to treasure（珍惜）food from a young age in different ways. Students need to return his empty plate at a school in Shanghai. The school starts the “Clear Your Plate” program to stop food waste.
A teacher tells stories about saving food before having meals at school in Xiangxi. The school hopes that children know it’s important to treasure food.
