This is the concept of "Han Feizi".

"Skillful deception" refers to the practice of deception and concealment. At first glance, "deception" may seem like a clever strategy, but as time goes by, the possibility of people around you becoming suspicious or even staying away increases. On the contrary, "sincerity" refers to doing things sincerely. The behavior may be relatively stupid, but it will win the hearts of most people. Han Feizi believes that instead of using clever methods to deceive others, it is better to treat others sincerely.
