The purpose of introducing male and female dining windows in school canteens is also to save food. Because the school also found that girls can't finish eating, so they also came up with such a way, the starting point is also to save food. Because men and women actually eat the same thing. But the average boy has a good appetite, and many times girls can't eat it at all, so the school has also introduced such a method, in order to raise everyone's awareness of saving food, let everyone know about the hard-won food and cherish the pages. ?

Therefore, when eating, we should also establish such a consciousness that we should learn to cherish food, because every grain of food is hard to come by, so as contemporary youth, we should set an example ourselves and have a good habit, and don't form a bad habit of wasting food. Cherish food, but also from small things, from yourself, from the side, so that people around you can also establish such a sense, not to waste food, because wasting food is also a poor performance. Because saving food is also a fine tradition of our country, we should also cherish it.

Moreover, while we cherish food, we are actually respecting the fruits of farmers' uncles' labor, because they actually work hard every day, so we should cherish it more. ?

Therefore, to sum up, the purpose of introducing male and female dining windows in school canteens is to enable students to save food.
