Siheyuan: Educated Youths Sent to the Countryside Get a Sign-In System

In November 1965, He Yushun came out of the street office, and the cold wind blew into his neck. How could he, a southerner, come to the capital in the 1960s? I opened my eyes a month ago and found that I had become an educated youth sent to the countryside, eating cabbage and potatoes every day, with very little oil and water. Fortunately, God didn't let him go in vain and provided a sign-in system. Although it is far behind other people's golden fingers, it is still better than nothing.
