In the cold winter of the 1960s, Su Qingyang woke up from the cold in a sour and shabby room and accidentally traveled to the world of a courtyard. As a regular worker at Red Star Factory, he has a stable livelihood and has to take care of his young adopted sister alone. Since then, I have been able to stand up for myself, live a down-to-earth life, and never let anyone take advantage of me.
