There is a famous saying "you want to spread" in the type communication of public relations. It can be seen that communication is a basic social behavior unique to human beings. The communication of public relations is a comprehensive communication behavior, which basically belongs to the level of organizational communication, but it has the characteristics of various communication types. From this point of view, studying different types of general communication will help to carry out the communication activities of public relations. 1. interpersonal communication. Autobiography, also known as autobiography, refers to the way of information exchange and communication between the two sides, such as personal self-reflection, memory, monologue, self-venting, self-comfort, narcissism, ideological struggle, inner conflict and so on. All sane people have autobiography. Through autobiography, people can realize self-psychological adjustment when they are subjected to various external shocks, so as to obtain successful and harmonious external communication. Interpersonal communication is the basis of all human communication behaviors. 2. Interpersonal communication. Refers to the direct exchange of information between people. This kind of communication is characterized by high participation, diverse communication symbols, rich means, flexible information feedback, strong emotional color, small scope and slow speed. For example, the emotional communication between men and women belongs to interpersonal communication. 3. Organize communication. It refers to the information exchange among organizations, the public and the social environment. The main body of this kind of communication is social organization. When an organization uses its closed communication, it is the internal communication of the organization, which has the characteristics of hierarchy and order; When an organization uses its open communication, it is the external communication of the organization, which has the characteristics of publicity and popularity, but it must be carried out with the help of the media. Whether it is internal communication or external communication, organizational communication has a clear purpose, that is, to achieve the goals of social organizations; It has strict controllability, that is, it obeys the overall goal of the organization and has good control performance; It has comprehensive characteristics, that is, because the target of communication is both individuals, groups and the wider public. Therefore, its means of communication include interpersonal communication, group communication, public communication and mass communication. This is typical public relations communication. 4. Mass communication. Refers to the way in which professional communicators copy a large amount of information to the dispersed public through mass media. The advantages are: the maximum propagation surface can be obtained in the shortest time; Because professional journalists are "gatekeepers" and mass media are "filters", the information disseminated is authoritative and convincing; Personal emotional factors are less involved and highly open. Disadvantages are: the information feedback is slow and scattered, and the workload of evaluating the communication effect is large. In view of its large volume and strong influence, mass communication plays an important role in quickly establishing organizational image and expanding organizational visibility, so it is the main means of public relations communication. 5. International communication. It refers to the exchange and transmission of information and ideas between countries. There are many functions of international communication: ① to exchange information needed by all parties, such as the introduction and export of science and technology, the exchange and discussion of academic views; (2) in order to publicize their own ideas, such as issuing statements, submitting notes, creating international public opinion, etc. ; (3) In order to establish and strengthen relations between countries, such as state visits, participation in international activities, cultural and artistic exchanges, etc. It is precisely because of the great role of international exchanges that "the two countries are at war, and they will not cut the envoy" has almost become an unwritten rule since ancient times, so even if the soldiers meet each other, the information exchange between countries must be guaranteed. In international communication, we should fully consider the influence of cross-cultural factors such as language, writing, customs, ethics, patriarchal ethics, politics and economy. Doing a good job in international communication is very important for a country to create a good international image and establish a good international environment, and it is also an important means to carry out international relations.
