Lin Chen opens a gym in a shopping mall and carefully develops high-quality service, keeping the establishment packed with customers year-round. At the end of the year, he generously gives every employee a 50,000-yuan bonus. However, several greedy fitness coaches demand enormous profit-sharing payouts. When their demands are rejected, they lead a large number of employees in resigning together, boasting that they can use their own abilities to steal the customers. They mistakenly believe the customer traffic comes from them, unaware that customers favor this gym because they appreciate its attentive and reliable service. Arrogant and ungrateful, these former employees open a new gym that attracts virtually no customers and eventually goes bankrupt under a mountain of debt. Meanwhile, Lin Chen remains true to his original principles, continues expanding his chain of gyms, and grows his business bigger and bigger. The story conveys a positive message: sincerity, gratitude, and thoughtful service are the keys to lasting success.
