Culture shock is an occupational disease (职业病) for people who have been suddenly transplanted abroad.

Culture shock is caused by the anxiety that results from losing all familiar signs and symbols of social intercourse. Those signs are as following: How to shake hands and what to say when meeting people, when and how to give tips, how to make purchases, when to accept and refuse invitations, when to take statements seriously and when not. These signs, which may be words, gestures, facial expressions, or customs, are acquired by all of us in the course of growing up and as much a part of our culture as the language we speak or the beliefs we accept. All of us depend on hundreds of these signs for the peace of our mind and day-to-day efficiency, but we do not carry most at the level of conscious awareness.

Now when an individual enters a strange culture, all or most of these familiar signs are removed. No matter how broadminded or full of good will you may be, a series of supports have been knocked from under you, followed by a feeling of frustration. When suffering from culture shock people first reject the environment which causes discomfort. The ways of the host country are bad Because they make us feel bad. When foreigners on a strange land get together to complain about the host country and its people, you can be sure that they are suffering from culture shock.
