This time coordinate controls people＇s behavior, awareness of concepts, industrial relationship, interpersonal relationship and value orientation. Different cultures bred different time conceptions and time behaviors. This paper mainly talks about the aspects of their differences. When different time views are reflected in cross-cultural communication, conflicts and obstacles of interpersonal communication may arise. With the development of social economy and cultural communication, the time views of Chinese culture and western culture have impacts on each other and are gradually integrated with each other.展开更多
