Siheyuan: Beat Everyone, Get Promotion and Salary Increase

In the winter of 1961, Zhang Qing traveled to the world of "Love in the Courtyard" and became a fatherless and motherless apprentice in a steel rolling mill in No. 95 Nanluogu Lane. The sanctimonious Yi Zhonghai, the official-obsessed Liu Haizhong, and the calculating Yan Bugui, the three stewards took turns trying to take advantage of this young man with no backing. Zhang Qing's handling method is simple and direct: If anyone messes with me, I will pay him back tenfold! He has this confidence because he carries a daily blind box system with him. From repairing machines to writing proposals, from apprenticeship to being a celebrity in the Ministry of Industry, Zhang Qing rose through the ranks and by the way married the daughter of the director of the Planning Commission. But just when he thought his life would go on like this, an anonymous letter was sent to the Public Security Bureau! Zhang Qing is suspected of being a major enemy agent. The person who wrote the letter did not want to embarrass him, but wanted him to die. Since they took action first, don't blame him for being cruel. The three stewards disappeared from the courtyard one after another. No one was seen alive and no body was found dead. "I am a reasonable person, but if anyone wants my life, I will send him on his way first."
