Intercultural communication is a form of global communication. It is used to describe the wide range of communication problems that naturally appear within an organization made up of individuals from different religious, social, ethnic, and educational backgrounds.As a separate notion, it studies situations where people from different cultural backgrounds interact. Aside from language, intercultural communication focuses on social attributes, thought patterns, and the cultures of different groups of people. It also involves understanding the different cultures, languages and customs of people from other countries. Intercultural communication plays a role in social sciences such as anthropology, cultural studies, linguistics psychology and communication studies. Intercultural communication is also referred to as the base for international businesses. There are several cross-cultural service providers around who can assist with the development of intercultural communication skills. Research is a major part of the development of intercultural communication skills.As we all know, there are so many differences between culture of the East and West that I can not list all of their different aspects. I will focus on the differences of diet custom and teaching system. For your better understand , I will set examples of China and America.It is no doubt that it is a tradition to use chopsticks for Chinese. But people in America prefer to forks and knives. This different result is based on different food they are like .Americans choose to eat beefsteak, bread, and salad, while Chinese people choose noodles, pancakes and rice. What is more, the custom of drinking tea in China and drinking coffee in America are stand out particularly .However, there is a trend that the food in both countries has been mixture. For example, the coffee and bread have introduced to China. The famous KFC is very popular at children.The gap of teaching system between China and America is big. Chinese students always complain about their homework. Too much homework has limited the time to exercise and relax. They have to recite many things as to get a high mark. Homework comes the first to them.In my opinion, the study in America is more interesting .Teachers pay attentions t o training students‟ skills in thinking in realistic life not to emphasis on the importan ce of memories. In a addition, the rate of going to school ,the salary of teaching ,and t he job of graduates are quite different, too. I should say that China government should make great efforts to improve its teaching system. I am also expect to be one day ,the West give more cheers to our country.“Culture is the collective programming of the mind which distinguishes the me mbers of one category of people from another.”It is inevitable that the cultural difference has impact on business. For example, when a company is having meeting, the word “table” they mention in American Engli sh means to put something on the agenda, but in British English it means to put somet hing off the agenda. This example indicated how the culture affects the business.In Western wedding culture and the first in the West in thinking about the differences: the Chinese people more conservative, like excitement, more old-fashioned thin king, so in the history of China for thousands of years the entire wedding customs did not change much. The thinking in the West is more open to the requirements of the we dding will be lower, they will be the climax of the wedding in the church: the sacred a s the "wedding march" into the red carpet, Jiao Mei's father, the bride linked hands Ro se walked slowly to the groom, the bride's father, daughter to the groom's hand on han d, her daughter's life will be entrusted to the groom, all eyes followed the couple, filled with well-being in their face. Second, the result of cultural differences wedding in the West because the West in a different religion. China is mainly Buddhist, but the Wes t is mainly Christian. Therefore, the Western wedding is to be held in the church and t he priest is Zhuhun Ren. China's traditional customs of the most important part of the Bai Tiandi is, the worship heaven and earth even after the ceremony has become.There are many differences between east and west,family just part of it.Different cultures add the most colorful element to the world of 21st century. The cultural gap s hould not be the obstacle to the civilization of human being. It ought to be the motivat ion of our going farther. When doing cross-cultural communication we will face many cultural collisions and frictions. we should think globally by acting locally and learn more about the different culture to do a better communication.。
