The elderly generally experienced the great famine of the 1960s. You can talk to your grandparents or other old people about the situation at that time, which is nothing more than why they didn't eat or drink at that time, but ate bark and grass roots. I really didn't bother to ask, so I looked it up online, handled it myself, and changed my name and number. Then, I will pull out some things I learned from textbooks and list all kinds of national data at that time, which can be found on the Internet. Then there is reflection, comparison, bitter experience, holding high the great banner, nonsense, finished writing!
