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~

In 1961, in the canteen of the Hongxing Steel Plant, a series of scenes unfolded, a microcosm of the era: a courtyard house? He Yuzhu, a time traveler... What is this? A bird? Let the curtain rise! Main characters: He Yuzhu, Qin Huairu

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?

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.

He Yuzhu's life, in the end, was a waste of his good intentions.

When he is given the chance to be reborn, everything will be different from before.

Yi Zhonghai, you're trying to scheme against me and morally blackmail me. Well, let's see who has the higher moral standard.

Qin Huairu, you've wronged me the most, so I'll just have to torment you for the rest of my life, otherwise my heart will never be at peace.

Liu Haizhong, taking care of your two sons is what you should be doing. Don't worry about anything else. After all, you're a high school student, so don't let others use you as a pawn.

Yan Bugui, you're so cunning, your children will probably be even more cunning than you when you get old.

He Yuzhu's rebirth will change the fate of many people, not just his own.
