Feng Ling, a takeaway rider who delivered orders during a heavy rainstorm, was deducted of all his savings due to a complaint, but found a business opportunity when he helped the elderly in the community purchase fresh food. From being deceived by a wholesaler into buying fake goods and losing all his money, to being threatened by local snakes to destroy the "warehouse"; from setting up a stall at a night market and hiding from the urban management and getting into the trash can, to struggling to get started by keeping accounts on the WeChat applet - he stepped in the mud and turned the corner of the rental house into a fresh food warehouse, and received every trust with sincerity. When a former classmate showed off his luxury car and ridiculed his "errands", and when an Internet celebrity wanted to buy his customer base at a low price, Feng Ling tightened the order in his hand and made community fresh food his own with the help of Aunt Wang's hot buns, Su Qing's order notes, and Lao Li from the express delivery station. This is not a cheating counterattack, but a story of every ordinary person falling down, standing up, and taking another step forward in life. Flowering in the mud is the most powerful.
