Wu Fan, a young man from the countryside, partners with his cousin Zhang Qishan to run a seafood shop. After working tirelessly for a year and earning 1.85 million yuan, Wu Fan receives only 80,000 yuan and is even humiliated as nothing more than a 'stinking shopkeeper.' Heartbroken, Wu Fan decisively ends their partnership and opens his own shop, 'Ordinary Seafood.' Zhang Qishan cuts off his supply channels, hires people to smash his shop, deliberately lowers prices, spreads malicious rumors, and even bribes someone to contaminate his seafood supply, using every dirty trick to crush him. However, Wu Fan sticks to his principles, sources seafood honestly, insists on the freshest quality, and provides sincere service. By retaining loyal customers and winning over major clients, he steadily grows his business into an even bigger success.
