Duan Yongping Discusses Business and Integrity: You can afford to lose money once, but if a person lacks integrity, never do business with them again. He personally witnessed bosses in Guangdong from earlier years who got rich through mutual deception. They appeared successful, but within less than ten years, they all disappeared, their money was stolen, and they ultimately became poor. What is cleverness? What is wisdom? Clever people know how to deceive others to make money; wise people understand that you can deceive for a moment, but not for a lifetime.
