Thirty-six years ago, on a stormy night, two babies were abandoned at the entrance of a courtyard house.

Three-month-old transmigrator Yi Hu, clutching his younger sister's swaddling clothes, crawled step by step to the door of Uncle Yi Zhonghai's house, driven by his survival instinct.

The moment the door opened, his fate was completely rewritten.

Amidst the everyday life and conflicts within the courtyard, Yi Hu never forgot the taste of survival in dire straits.

He studied diligently and overcame numerous obstacles to gain admission to Tsinghua University, using knowledge to unlock the door to his destiny.

Is there hidden risk in staying on as a faculty member?

Is the pace of going down to the grassroots level for experience too slow?

Qi Hu insisted on taking a different path, relying on his solid professional skills and extraordinary courage to directly enter the ministry—the Ministry of Water Resources and Electric Power—to write his own legendary story of a comeback on a broader stage.

Yi Jizhong travels back to 1958, where his mother tells him before she dies that his father is still alive.

Yi Jizhong came to the capital to find his father, but he never expected that he would be in a world of courtyard houses, and that his father was Yi Zhonghai, the Moral Celestial Venerable.

From then on, there was one more person in the courtyard who acted arrogantly and domineeringly.

Sun Bin joined the 200,000-strong Siheyuan trek and connected to a daily intelligence system, gaining complete knowledge of the Siheyuan's trivial affairs. But how did this make me a relative of the Jia Zhang family? And they're even going to marry Qin Huairu to me? What should I do? Waiting online, feeling quite anxious!

Chen Yang woke up and traveled back to the story of the courtyard house. He became a purchasing agent at the supply and marketing cooperative in the alley and led his family into a happy and well-off life with great strides!

Dad Zheng Fuguo: The "stinky old nine" who cleans toilets in the steel rolling mill has a precarious status as a temporary worker and is someone who can be stepped on by anyone in the yard.

The eldest brother Zheng Guang: an apprentice in the boiler room of a steel rolling mill, was used as a "fire stick" by the canteen helpers headed by Sha Zhu, and was covered in coal dust and could not lift his head.

My mother: Because of my class background, gossipers like Jia Zhang framed me as a "jinx," causing my entire family to be looked down upon and forced to fetch water in the middle of the night. My younger sister was as thin as a bean sprout. The children in the yard would often snatch her steamed bread and throw cold water on her. She couldn't even cry out loud.

Zheng Yang relied on the Golden Finger System, many years later...

Sha Zhu: Now I am the canteen team leader of the steel mill.

Zheng Yang: Very good, my brother is now the factory manager!

Jia Zhang: Finally, I can eat meat during the Chinese New Year.

Zheng Yang: Eating meat? We’re tired of seafood at home!

Qin Huairu: Our Xiaodang is a new generation of worker-peasant-soldier college students.

Zheng Yang: Excuse me, my little sister is a recent graduate of Peking University or Tsinghua University, and she got a job right after graduation! How can you compare with my family?

…

All the birds in the hospital were collectively defeated!
