In the late 1980s, Lin Xiangnan fails the college entrance exams. Facing debt and mounting pressure, he refuses to give up and instead finds a way forward through the river snails nobody in his hometown wants. From cleaning away their fishy smell and perfecting seasonings to opening up a market in town, he gradually establishes himself. When competitors try to sabotage him, supplies become unstable, and technical problems arise, he remains committed to honest business practices and transparent accounts. He leads his fellow villagers in collecting and farming snails, transforming muddy ponds into ponds of prosperity. At the profit-sharing meeting, every household receives its share of the earnings. This is an inspiring story of an ordinary rural young man who changes his destiny through hard work and integrity.
