Zhang Lin is a retired football player who founded a football manufacturing factory with his childhood friend, Li Qing. Drawing on his knowledge of football, he worked hard for years and secured numerous orders, eventually winning a contract to supply footballs for the World Cup. Just then, his business partner and childhood friend, Li Qing, fired him on the grounds that Zhang Lin had repeatedly failed to meet the company's attendance requirements. Furious, Zhang Lin left the factory. Li Qing thought he had won, but the quality of the footballs soon plummeted, orders were canceled one after another, and even the World Cup contract was lost. With the help of his wife and parents, Zhang Lin mortgaged his property, established a new factory, successfully secured the World Cup order, and ultimately became a World Cup supplier.
