Su Chengyuan establishes an eco-friendly pig farm and scientifically raises pigs using fermented feed made from substandard fruit rejected by fruit merchants. Despite misunderstandings and numerous obstacles, he remains committed to honesty and integrity. He builds a sustainable ecological cycle in which substandard fruit feeds pigs, pig manure is turned into organic fertilizer, and the fertilizer is used to grow fruit trees. By doing so, he helps thousands of nearby fruit-growing and livestock-farming households increase their incomes and build wealth, forging a prosperous path toward rural revitalization through hard work.
