Programmer Lin Feng accidentally traveled to the world of "Love in the Courtyard" in the 1960s because of working overtime and staying up late to watch TV dramas, and became an ordinary steel factory worker. Being bound to the "neighborhood relationship system", he shoulders the task of improving the lives of courtyard residents and promoting neighborhood harmony.
Faced with neighbors with very different personalities: the righteous but honest He Yuzhu, the tolerant but shrewd Qin Huairu, the cunning and calculating Xu Damao, and the uncle Yi Zhonghai who is well versed in the courtyard's rules, Lin Feng relied on modern wisdom and systematic golden fingers to resolve conflicts and difficulties step by step, and gradually became the "smart star" of the courtyard.
However, with the advent of the Cultural Revolution and the dawn of reform and opening up, life in the courtyard gradually entered the torrent of historical changes. How does Lin Feng use his own power to change the fate of the residents in the courtyard? When the happiness index reaches its peak, can he truly return to his own era?
Traveling through the courtyard, warmth and wisdom coexist, and even a small person can achieve a big future!
