In the midwinter of 1985, Zhou Dongbei was reborn and returned to the year before his sister Zhou Dongnan was forced to get married and jumped into a river. Faced with the forced marriage of the Wang family and his father's huge debt of 1,490 yuan, he took an ax to protect his sister, toughened up the scoundrels, and dug out 100,000 kilograms of food stamps based on his memories of his previous life. He decisively stopped his job without pay and ruined his iron job. He teamed up with two young men and old prostitutes, and started a business by exchanging food stamps for eggs. Riding around the countryside to collect eggs at 30 degrees below zero, outsmarting philistine directors and hard-nosed gangsters, relying on ruthlessness and a sense of business opportunities, a poor boy with only three and a half yuan in his pocket turned his back on the road and became a household worth ten thousand yuan, protecting his family and living a hot life in the wave of reform and opening up.
