In 1965, Lin Ye's parents died unexpectedly in Liushu Hutong, Beijing, leaving behind only a wooden box containing food stamps, "Agricultural Machinery Factory Technical Notes" and "Street Work Manual" - this was his entire "family fortune".
But the white-eyed wolves came one after another: Mrs. Zhao blocked the door to grab food stamps and said, "I will help my grandson to replenish his health."; Director Sun of the agricultural machinery factory changed his machine tool drawings in the hope that he would be fired; Uncle Wang in the courtyard stared at the land deeds and pretended to come to "escrow".
Lin Ye didn't get used to it: he looked through his mother's manual to find policies, which left Mrs. Zhao speechless; based on his father's technical notes, he exposed Director Sun's little tricks on the spot, making the factory director scold him; he discovered that the date of the land deed was strange, and followed the clues to find out the secret behind his parents' death.
During his days, he hoarded meat stamps from coal piles to improve his life, hid "How Steel Was Tempered" with Shen Qing in the coal shed to pass on information, and at the street mediation meeting, he threw out the account book of Uncle Wang's misappropriation of funds to seek justice.
When the college entrance examination resumed in 1977, Lin Ye dug out his parents' old textbooks and Shen Qing handed over the review materials in the cover of the Little Red Book. He suddenly understood that what his parents left behind was not just material supplies, but also the confidence not to be overwhelmed and the hope of counterattacking with knowledge.
Later someone asked what was the most precious thing about the courtyard house? Lin Ye pointed to the tattered notes and touched the pen given by Shen Qing: "It's the hard work of my parents, the backbone of not being a white-eyed wolf, and the people who accompany me to guard this."
