In the early 1990s, ordinary young man Lin Chunsheng and his wife, Zhou Huilan, set up a breakfast stall at the entrance to their old neighborhood. On opening day, a customer immediately points out an error on the first page of their ledger. Lin Chunsheng then faces a series of challenges: not having enough change, overdue payments for supplies, and a neighboring vendor urging him to "shortchange customers by a few cents—no one will notice." Lin Chunsheng chooses to correct the accounts in public, return the missing change, and display a detailed breakdown of the transactions. From an embarrassed beginner, he gradually learns to run his business with integrity. In the end, his first customers voluntarily help spread the word, and his little stall establishes itself through honest craftsmanship and transparent bookkeeping.
