Zhao Xudong, who has worked in the seafood market for twelve years, was kicked out by his childhood friend Li Yaozong simply for insisting on adding three yuan for a fresh-keeping package to the goods. Faced with the ridicule of the entire market, he teamed up with Shen Manqing, the owner of a stall on the verge of bankruptcy, carrying an old ledger, and established iron rules of no water adulteration and no short-changing on weight. Who would have thought that just as business was picking up, the old boss would cut off ice, cut off supplies, destroy equipment, and even resort to underhanded methods. Relying on his mastery of freshness-identification skills and years of accumulated supply sources and connections, Zhao Xudong repeatedly broke deadlocks, secured orders worth tens of millions, and led fishermen to unite and turn the tables. From a small fish tank to a listed aquatic products group, he used a scale to slap everyone who looked down on him in the face!
