The principle of reciprocity holds that we should try our best to repay others for what they have done for us in the same way. To put it simply, it means that we should repay others with a similar behavior. If someone gives us a certain advantage, we should repay others' kindness with another advantage. We can't be indifferent to it, let alone repay virtue with resentment. Therefore, the most effective weapon of influence around us is used by some people to seek benefits.
There is a Chinese saying: eat someone's mouth soft, take someone's hand short. No one wants to be called a cheapskate by his colleagues or friends. Once he is invited by a friend, he should firmly remember how much he spent on the other party's invitation, and strive to invite the friend back as soon as possible, and plan to spend the corresponding amount. This is actually the psychological effect of reward.
