Lin Xiangyang manages his great-uncle's watermelon business. In one year, he generates three million yuan in revenue but receives only 50,000 yuan in compensation. Disheartened, he decides to return to his hometown and grow watermelons independently. He painstakingly studies cultivation techniques and overcomes one challenge after another, including crop diseases, market fluctuations, and difficulties finding buyers. With superior quality and reliable distribution channels, he turns his fortunes around and builds his wealth. Eventually, he lets go of past grievances and leads the villagers of Qinghe Village to grow watermelons together and increase their incomes.
