Craftsman Lin Deyou rescues Doudou, a child who fell from a building. Grateful for the kindness, the child's grandfather rents a storefront to him for 60,000 a year to open a lamian noodle shop. With his solid skills, Lin Deyou makes the business thriving. Seeing profit to be made, the landlord's son Qian Zhiyuan abruptly raises the rent to 150,000 upon expiration. Lin Deyou decisively moves away all his own equipment and looks for a new shop to reopen. Qian Zhiyuan and his wife take over the store, single-mindedly pursuing profit by cutting corners, constantly losing customers. In contrast, Lin Deyou sticks to quality, providing caring service to construction site and hospital guests, and his business is booming. After several failed tosses, Qian Zhiyuan is investigated for misusing the trademark, and finally, the shop is transferred at a loss, missing the cooperation opportunity due to greed.
