Concept cultivation
Let children understand that food is hard to come by and learn to cherish it. You can take your children to the countryside to experience the hard work of farming and watering, and let them understand that "every grain is hard".
lead by example
Parents need to be good role models for their children. Only by not wasting food can their children get a good education.
Set a good example
When eating out, parents should order less meals and pack leftovers to set a good example for their children to save. On buffet occasions, children should be educated to eat in moderation and not to form the habit of wasting at will.
