The core of interpersonal communication is cooperation and communication. To cultivate communication skills, we must first have a positive attitude, understand others and care about others. In daily communication activities, we should take the initiative to communicate with others, don't avoid passively, dare to contact, especially dare to face people different from ourselves, and don't be afraid of birth, appearance and experience. Don't shut yourself off just because they come from remote areas, and don't shut yourself off just because they are ugly or less experienced than others. Secondly, we should start from an early age and pay attention to social etiquette. Thirdly, we should be good at doing things, boldly go out of school, eliminate fear, strengthen knowledge accumulation in communication, experience in actual communication life, and master various methods and skills in interpersonal communication. In addition, we should realize that in dealing with people, what is touching is sincerity, sincerity in making friends, sincerity in doing things, and sincerity can be exchanged for cooperation and communication with people. Sincerity is always one of the most precious feelings of human beings.

1. Principles of interpersonal communication

(1) principle of equality: in the interpersonal communication in socialist society, we must first adhere to the principle of equality. Whether official or individual, there is no distinction between high and low. We must communicate like friends in order to make deep friends. Don't feel inferior because of short working hours, lack of experience and poor economic conditions, and don't be arrogant because you are a college graduate and young and beautiful. These mentalities all affect the smooth development of interpersonal relationships.

(2) Compatibility principle: mainly psychological compatibility, that is, harmonious relationship between people, tolerance, tolerance and forbearance when getting along with others. Take the initiative to communicate with others, make friends widely, make good friends, not only with people who are similar to themselves, but also with people who are opposite to themselves, seek common ground while reserving differences, learn from each other's strengths, handle the relationship between competition and compatibility, and better improve themselves.

(3) Principle of mutual benefit: refers to mutual benefit. Interpersonal communication is a two-way behavior, so there is a saying that "come and not go, make trouble without reason", and interpersonal communication that benefits unilaterally cannot last long. Therefore, both sides should benefit, not only materially but also spiritually, so both sides should pay attention to dedication.

(4) Credit principle: communication is inseparable from credit. Credit is a person's honesty, integrity and trustworthiness. As the old saying goes, "A promise is worth a thousand dollars, and a promise is worth a thousand dollars". Now there is an honest principle. Don't promise easily. Once you make a promise, you must work hard to realize it, so that you will not break your promise. Between friends, what you say must be done, and what you do must be done. You are neither supercilious nor reserved, modest but not pretentious, not bullying or being afraid of hard work, not arrogant and impetuous, please highly respected people, show your self-confidence and gain the trust of others.

(5) the principle of tolerance: it is manifested in not haggling over the unprincipled issues, being able to repay evil with good, and being tolerant and generous. Misunderstandings and contradictions often occur in interpersonal communication. College students have strong personalities and close ties, which inevitably lead to contradictions. This requires college students not to haggle over every ounce, to be modest, generous, restrained and patient, regardless of each other's attitude and words, to be brave enough to bear their own behavioral responsibilities, "to let the prime minister punt in his stomach", he quarrels, but you don't quarrel; He is fierce, you are not; He scolds, but you don't. As long as we are broad-minded and tolerant of others, the angry party will get bored. Tolerance and restraint are not signs of weakness and cowardice. On the contrary, it is a measurable performance, a lubricant for establishing good interpersonal relationships, and can "turn enemies into friends" and win more friends.
