Gu Beishan, who returned from military service, came to Beicha Village. During a matchmaking session, he took a fancy to Du Fengxia, who excels at raising pigs, and the two became husband and wife. Facing the disdain of relatives and the malicious suppression of industry competitors, the couple joined hands with one heart to overcome heavy difficulties such as capital shortages, spoiled feed, rumor-mongering, and unfair competition from competitors. They learned scientific breeding, established complete breeding ledgers, led the fellow villagers to develop a contract-raising model, secured a Hong Kong-supplied live pig order, and achieved prosperity through hard work. The old past between the older generation was also slowly unveiled, and the family let go of their knots, making their days more and more prosperous.
