For example, in college, learning modern etiquette helps college students to establish good interpersonal relationships with others, form a harmonious psychological atmosphere and promote physical and mental health. With the growth of age and the change of living environment, the self-awareness of contemporary college students has made new progress, and they are very eager to get real friendship and have more emotional exchanges. Generally, college students live a collective life far away from their parents in their hometown and are equal with other students. We have lost our previous dependence on our parents' "blood relationship" and "unconditional". Therefore, it is the need to adapt to the new living environment and develop from a "dependent" person to an "independent" person through interpersonal activities. At the same time, mastering modern etiquette will help us make ends meet in interpersonal communication in universities, thus improving our self-confidence and self-esteem.

People need to learn a lot in the process of socialization, and modern etiquette is an indispensable and important content in the process of socialization. Etiquette is a compulsory course in the whole life journey. Anyone who lives in a certain etiquette and standard environment is consciously or unconsciously bound by etiquette. People who consciously accept social etiquette are recognized as "mature people" and meet social requirements. On the other hand, if a person does not obey the etiquette requirements in social life, he will be regarded as a "heresy" by people in society. Society will restrain him by means of morality and public opinion. College students have a strong demand for going out to society when they graduate, but there are also some psychological puzzles, such as how to deal with leaders and colleagues, how to establish good interpersonal relationships, how to design self-image and so on. How to adapt to social life and other social communication issues as soon as possible? However, the social psychological endurance of college students directly affects the quality of communication activities. A person with a good etiquette foundation can always maintain a calm and stable psychological state when encountering various situations and difficulties in communication activities. According to the information he has, he can quickly take the most reasonable action to save the day and strive for the initiative. On the contrary, some people who don't know etiquette often have panic, fear, anxiety and fidgeting before participating in major communication activities, and some even have rapid heartbeat, trembling limbs and abnormal tone after the communication activities begin. Then, modern etiquette education will enable college students to master all kinds of behavioral norms that meet the social requirements, which will not only meet the needs of college students to go to society, but also better promote their socialization; It can also cultivate college students' ability to adapt to social life.

When interacting with colleagues, don't swear in person, and try to be tactful when refusing and criticizing, because everyone has face and only likes to pat his face instead of discrediting it. When you are in contact with the boss, you should also pay attention to strategy. For example, the boss has assigned you a difficult task, and you don't want to accept it, but after you know the etiquette, you will say to him: OK, I'll do it. Maybe after you say this affirmative sentence, the boss will think of you when you get promoted next time. This is because the boss may ask many employees to be reluctant, but only you take the initiative to accept the task. Think about it, in fact, the boss won't blame you for doing well, just because you have a positive attitude. Therefore, in interpersonal communication in the workplace, etiquette can not be ignored.

Looking at the development of market economy in modern society, it has brought about extensive division of labor and commodity circulation relations, promoted interdependence and cooperation between people, organizations and regions, and also brought about fierce market competition.

For an enterprise or service industry, it is more necessary to actively adapt to this change from "seller's market" to "buyer's market", and this change always needs specific people to implement and operate. If these practitioners don't understand modern social etiquette, it will be difficult for them to gain a foothold in the market. For example, it is impolite and even misunderstood for suppliers to come in without knocking at the door in advance. The so-called "courtesy is not strange." People should not only learn modern etiquette for themselves, but also for organizations and establish interpersonal networks under the conditions of market economy. Good interpersonal relationship helps them to go to the market smoothly, leave the unit and pave the way for their career.
