Zhang Hongmei, a shrimp-peeling worker, thinks Shen Qinghe's workshop pays too little and requires workers to wear protective gloves. She takes her coworkers and switches to Donghai Cold Storage, lured by the higher rate of 2.5 yuan per jin. But only after starting work there do they discover the harsh rules: minimum quality standards, weight deductions for draining water, and layer upon layer of penalties that squeeze every last bit out of their wages. They must even pay for their own irritating preservative solution. When one worker's hand is injured by a shrimp shell, nobody shows her any concern. Meanwhile, Shen Qinghe stands firm on workplace safety, refusing to exploit her workers through tricks and hidden deductions. Thanks to her high-quality shrimp meat, she secures long-term orders from restaurants, making the superiority of her honest business practices clear.
