E.T. Hall proposes that China is a high-context culture, in which utterance meaning can be interpreted not only in verbal language but also from non-verbal behaviors. The paper tries to explain the underlying social factors that influence the Chinese high-context orientation, and finds that Chinese traditional philosophy as Confucianism, Taoism, Buddhism, Chinese economic form and development, and Chinese peculiar but long-standing education system affect Chinese people's communication patterns deeply and eventually form a high-context culture orientation. The author demonstrates arguments with such exemplifications as historical facts, cultural allusions, folk stories and so on, aims to display Chinese traditional communication modes to other countries, and at last, calls on world citizens to recognize cultural diversities in the process of cross-cultural communications.
