China has stepped up measures to reduce food waste, after President Xi Jinping called the amount wasted "shocking and distressing".
The "Clean Plate Campaign" comes after Mr Xi highlighted that Covid-19 had "sounded the alarm" on food waste.
He added that China had to "maintain a sense of crisis about food security".
It also comes after weeks of mass flooding across southern China which left farms wrecked and ruined tons of produce.

State TV also criticised livestreamers who filmed themselves eating large amounts of food.
Following Mr Xi's message, the Wuhan Catering Industry Association urged restaurants in the city to limit the number of dishes served to diners – implementing a system where groups must order one dish less than the number of diners.

In a group setting, empty plates are sometimes seen as a sign of a bad host – signifying that an insufficient amount of food was ordered for guests.
The "N-1" idea faced some criticism online, with some pointing out that it was "too rigid".
"What if one person goes to a restaurant alone? How many dishes can he order? Zero?" asked one person on microblogging site Weibo.
Others said that most restaurant diners did not normally waste much food, pointing instead to extravagant banquets thrown by officials.
Chinese state agency CCTV also called out livestreamers who typically film themselves eating large amounts of food.
