What did grandparents eat when they were children; What did mom and dad eat when they were children? What should I eat now?
Grandparents were very poor when they were children, and they often couldn't eat. Mom and dad ate some coarse grains when they were children, but they didn't have enough to eat. Usually, a food can last for several months. What I eat now is very nutritious, and I can eat enough at every meal. So we should cherish the present time, study hard and live up to the expectations of our elders!
