With a cold wave approaching, fruit merchant Zhou Cheng returns to his village and offers to buy all the oranges for the high price of four yuan per jin. However, incited by Wu Daqiang, the villagers drive him away. When the cold wave arrives as predicted, all 3,000 tons of oranges in the village freeze and are destroyed, leaving the villagers with nothing. They kneel and beg Zhou Cheng to buy their frozen fruit, but he refuses. Instead, Zhou Cheng partners with a neighboring village to build cold-storage facilities and a sorting center, signing long-term contracts and helping farmers withstand natural disasters. After overcoming torrential rains, malicious competition, and other challenges, he eventually builds the 'Liping Orange' brand, brings prosperity to the entire community, and earns the villagers' trust and respect.
