An accident sends Zhang Ping'an back to the early days of the People's Republic of China, where he becomes Jia Zhangshi, the half-brother of Zhang Xiaohua. The siblings are 21 years apart in age. Old Jia is rescued at the beginning, and He Daqing does not go far to Baocheng. Will Yi Zhonghai and the deaf old lady still be able to control everything in the courtyard?

Yan Jiecheng, a small-time machining boss, travels to the world of "Courtyard Love" and becomes a supporting character of the same name. However, he uses his knowledge left over from the modern era to change the plot and strive to become the protagonist.

I'm a bit confused. I just went on a budget trip, how did I become a fool for no reason? Well! Since I'm here, I might as well make the best of it. At least I don't have to worry about eating bread every day. Although this era is materially scarce, the people of this era are simple and kind! The happiness index of life is high! ~Okay! Except for this man-eating courtyard and the beasts living in this courtyard~

Li Jiang transmigrated to a traditional courtyard house and was bound to a fishing lottery system. Resources, skills, and techniques all depend on lotteries! Yi Zhonghai's forced donations and moral blackmail? I won't tolerate that, I'll fight! Qin Huairu trying to leech off me, coming to my door in the middle of the night? I don't want a widow like you! In this courtyard house, anyone who dares to mess with me will meet a terrible end!

Returning to the courtyard house filled with love, he becomes Qin Huairu's fiancé. There, he encounters two cooks, Sha Zhu and Nan Yi. Qin Huairu: "Jia Haoyun, I just like you." Sha Zhu: "Haoyun, look how old I am! Can you introduce me to someone like your sister-in-law?" Liang Ladi: "Haoyun, thank you!" Witness the love, hate, and entanglements of Jia Haoyun, a modern-day nobody, as he travels back to a turbulent yet innocent era.
