The middle-aged social worker Xu Yaping died suddenly while working overtime. When he opened his eyes, he traveled back to the old Beijing courtyard in 1961 and became the biological brother of Xu Damao. At that time, the Xu family was extremely poor, Xu Damao was selfish and stingy, and the courtyard house was full of the best - the dog-licking fool Zhu, the greedy Qin Huairu, the calculating third uncle, and the eccentric deaf old lady, all of whom wanted to take advantage of the Xu family. There is no system and no golden fingers. Xu Yaping relied on modern experience and understanding of the plot to correct Xu Damao first. The two brothers changed from disliking each other to being brothers and respectful brothers. Together they are filial to their parents and protect their sister. In special times, he kept a low profile, avoided pitfalls, and quietly saved money. After opening up, he seized the opportunity. Relying on Xu Damao's screening experience and his own business thinking, he started from open-air screenings, founded a film company step by step, and became a billionaire through counterattack.
