The Hongcaowan Paper Mill was ordered to shut down due to sewage discharge issues, causing an uproar in Hongcaowan Village. Jin Cheng, the village party secretary and also director of the village committee, adopted the suggestion of Professor Jin Gu from the Agriculture University, leading the people of Hongcaowan to overcome numerous difficulties. They established an ecological pig farm and planted green crab field rice. However, in order to buy time for repayment of debts, Jin Cheng injured himself, sparking a significant "investigation" incident; Professor Jin Gu invested all her family's savings into ecological agriculture without her husband's knowledge, leading to irreconcilable conflicts with him; Jin Cheng's wife lost her life while trying to save Chun Ya, a misguided young rural woman; the ecologically-raised pigs ready for slaughter failed inspection, putting the ecological pig farm on the brink of disaster. Faced with various pressures, Jin Cheng, with his sense of responsibility and wisdom, led the entire village gradually out of difficulties, establishing an ecological agriculture cooperative, enabling the land to adopt a new management model, accelerating the process of agricultural industrialization and mechanization.
