Cross-cultural communication refers to the communication between individuals from different cultural backgrounds, that is, the interaction between people from different cultural backgrounds. In recent years, it has attracted the attention of most people. In China, language teachers show great interest, which reflects the changes and requirements of the times and attracts people to think deeply about foreign language teaching from the perspective of cross-cultural education.

Three basic purposes of intercultural communication. First of all, cultivate people's positive attitude towards different cultural understanding. Culture is a kind of difference. By discovering their differences, we can deepen our understanding of our own culture, so as to grasp our cultural identity objectively. In the process of finding differences, we should pay attention to many common points that cannot be ignored. Second, cultivate the adaptability of cross-cultural contact. When they come into contact with different cultures for the first time, they will be subjected to Cultule shock, which will lead to some inadaptability. In order to continue communication, we must seek to reduce the impact and improve adaptability. Third, cultivate cross-cultural communication ability. With the further expansion of opening to the outside world, more and more people go abroad or stay at home to participate in cross-cultural communication. They need to learn and master practical skills in dealing with people from different cultures. Cross-cultural communication is more meaningful in practice than in theory.

Three basic contents of intercultural communication. First, the world outlook and values; second, the cultural characteristics of speech acts; third, the study of nonverbal communication. The so-called world outlook is people's fundamental view of the world. It's just the relationship between man and nature, and the East and the West have completely different views. Western culture believes that man should be the master of nature and the object of conquering nature, and that man can constantly improve and use science and technology to transform and conquer nature, which is the center of things. In this regard, oriental culture believes that man and nature are a kind of coordination, and they are closely related, not to transform human nature, but to adapt to nature and use natural conditions to serve mankind. The so-called values are the criteria for judging good or bad, right or wrong, which will guide people's actions in a certain direction. Accordingly, it constitutes the skeleton of values, culture and social structure. For some literate people, what behavior is good, not what behavior is dominated by values. Values are an abstract concept, and it is difficult for people to grasp it, but we can often get a glimpse of some cultural values through language or language behavior patterns.

In the process of cross-cultural communication, the values hidden in the depths of culture cannot be avoided. It is through the understanding of different values that the understanding and understanding of cross-cultural communication is deepened. This is because when problems arise in cross-cultural communication, they arise when different values confront each other.

Cultural identity of language is another important topic in cross-cultural communication. Culture has distinct personality, and different cultures will naturally have differences. Cultural differences are reflected in language, and language becomes differences. Language is the product of culture, and culture is an expression of language. The use of language follows certain cultural rules. In other words, culture determines thinking and language determines expression. Let's imagine a foreigner learning Chinese. Foreigners should learn how to use the sentence "What I said is superficial, not criticizing the local revision" correctly. Besides the knowledge of the language itself, they must also acquire the social and cultural knowledge of China. You don't need social and cultural background and knowledge to create sentences, almost all the facts or the state of the film. For example, "I am a college student", "My big garden" and so on, these sentences are excusable in any language. However, the literal translation of many sentences in the past either failed or did not conform to the other party's social and cultural rules, rather than being understood.

The last nonverbal communication of the study. Nonverbal behavior and verbal behavior are often given different meanings due to cultural differences. In the process of cross-cultural communication, it is often misleading because of different interpretations of nonverbal behavior by different cultures. From the physical characteristics of people wearing clothes to goods, from sound to the level and color of room furnishings, from the concept of time to the concept of space, these are all factors of non-verbal communication. Japanese bow, Europeans and Americans hug and kiss, and Latin Americans pay tribute to all depilators to show their cultural identity.
