This drama tells the story of cold-chain driver Chen Zhiming, who encountered groundless extortion by a merchant while delivering goods, while market management favored the merchant and forcibly demanded three thousand yuan. To secure subsequent orders, Chen Zhiming was forced to pay, but chose not to swallow his anger, retaining all recordings, driving, and traceability evidence. When the other party distorted facts to incite cyberbullying, he produced complete evidence to restore the truth and defend his legitimate rights and interests. After the incident, Chen Zhiming, who firmly adhered to the bottom line of integrity, gained numerous long-term cooperations, while the untrustworthy market paid a heavy price. The story tells us that doing business and handling affairs must strictly adhere to integrity, and when encountering injustice, one must retain evidence and bravely defend rights, as reputation is the foundation of establishment.
