Chen Yuanshan, a sanda champion who came from Majia Village, has bought the villagers' waxberries for 30 yuan per jin for three years and sold them to outside markets for 60 yuan, generating nearly 12 million yuan in additional income for the village. He has even supported his fellow villagers with his own money. Ma Jun, the village chief's son, distorts the contract price and incites the villagers to ostracize him. Heartbroken, Chen Yuanshan turns to a neighboring village to develop his business. Ma Jun and his accomplices try to lease the waxberry orchards at low prices, but their venture ends in disaster, and Ma Jun is arrested for fraud. When Majia Village falls into hardship, Chen Yuanshan continues to quietly help the elderly. Now, he stands firm on his principles and protects his dignity by adhering to commercial rules.
