Everything must be divided into two, the policy is good and the implementation is wrong. It can be said that this policy was not perfect at that time, or the starting point was different. As a young graduate, he will not only go to the countryside, but also go to factories and troops to exercise. Perhaps the country did not have such conditions at that time, and now he has such conditions, but he has no such idea. If the young people who went to the countryside at that time had a professional team designated by their superiors and then combined with the "poor lower middle peasants" (this process required a lot of specific plans, was there at that time? It can be said that the slogan is very bright and there is no specific way. After several years of exercise, the young people who come back are far more useful than the "nerds" now. Everything is, no matter how good the policy is!
