In his previous life, Zhou Jianguo was famous for being an honest, unassuming man. He gave his relocation compensation to help his younger brother get married, handed over his hard-earned money to help his older brother start a business, and devoted himself to caring for his sick parents. Yet all his sacrifices only left his wife and daughter struggling to survive on scraps, until his family eventually fell apart! When he was gravely ill in his old age, the very relatives he had supported with everything he had actually wanted to pull the plug on his ventilator just to save money! Filled with endless regret, Zhou Jianguo is reborn in 1980, on the eve of his family's separation. Armed with memories of his previous life, he starts from selling a pot of foul-smelling offal, then sets up a street stall, opens a restaurant, and eventually establishes a food factory.
