Liu Minghui went back to 1957. In that era when material life was not very abundant, he successfully became a worker in a steel rolling mill and lived in a courtyard house by relying on the abundant space and materials.

It mainly tells the story of Liu Minghui's daily life in the steel rolling mill and the courtyard, with little violence.

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~
