Education is an important tool for cultural communication. It is not only an important tool for cultural communication, but also an important tool for cultural exchange. Education transmits culture, so that the new generation can quickly, economically and efficiently possess the essence of spiritual and cultural wealth created by human beings, and make a person change from a "natural person" without cultural content into a "cultural person" with the ability to absorb, appreciate and create culture. If human culture is not passed from the previous generation to the next generation, then the preservation, accumulation and development of human culture will become absolutely impossible. Any generation of new people must repeat what their predecessors have experienced, so human beings can't evolve, and they can only stay in the age of ignorance and may disappear from the earth at any time. Human beings are the creators and inheritors of culture, which is in terms of the whole human being with alternating generations. As far as each generation is concerned, the first is the inheritor of culture, and the second is the creator of culture. Only by inheriting culture first can we create culture. "People create their own history, but not at will, but under the conditions of direct encounter, which is established and inherited from the past." Generally speaking, the contribution of each generation to the progress of human culture is in direct proportion to the cultural heritage left by ancestors. Education spreads culture, in terms of its significance to individual survival and development, the process of receiving education is also the process of obtaining indirect experience. No individual can survive without indirect experience, let alone development. As we all know, a child born with sound voice organs cannot learn to speak or even form human thinking if he is not in contact with human society after birth. The so-called "wolf child" is a good example. Education transmits culture, internalizes human spiritual wealth into individual spiritual wealth and becomes a part of the whole life. In this way, the spiritual wealth of human beings has found its most stable, coexisting with human beings and having the function of regeneration. Therefore, education, as a means of spreading culture, has the function of preserving culture. Education communication culture is essentially a process of spiritual and cultural reproduction. This breeding process is economical, efficient and fast. "Scientific reproduction and scientific reproduction need labor time is incomparable. For example, students can learn the binomial theorem in an hour. " This reproduction process of spiritual culture is an interactive process between educators and educatees, and a process in which educatees constantly reorganize and construct their own subjective spiritual culture under the influence of objective spiritual culture. The research of anthropologist Gregory Bateson proves the above viewpoint. In his book Steps of Ideological Ecology, batson emphasized such a viewpoint: "Culture itself is complex, and the process of learning culture is also complex. In a sense, every generation has a process of rediscovering and understanding its own culture. Each generation not only learns its own culture, but also reorganizes its own culture. " Here, we are not going to discuss the complicated mechanism of cultural communication through education, but just want to emphasize that education, as a means of cultural communication, has the function of preserving culture. In the process of human generation alternation, it is indispensable to the whole human race and any individual.
