My friend Dr. Dong had a wonderful chance to go to Seattle to present a paper at a professional meeting. When he got back to Beijing, he told me his experience.

Dr. Dong enjoyed his first days very much. At the medical conference, he felt quite confident in his area of research and was able to perform well in his presentation. But after a few days, he began to feel uncomfortable. His medical English was fine, but the social communication skills were different.

He got more and more worried that he was misunderstanding simple English greetings and table talk conventions(习俗). When someone greeted him with, “Hi, how’s it going?” he thought they had asked him “Where are you going?” and answered with the name of the conference hall, only to get a surprised stare from them. At a western style dinner, a colleague asked, “So how’re you enjoyin’ the States?” he thought he heard, “how are you enjoying your steak?” and answered that he was eating chicken, not beef. That time, they smiled, and patiently repeated the question, then both laughed at the error.

By the end of the meetings, Dr. Dong felt a deep sense of “cultural stress” and was worn out from having to pay attention to so many new expressions and ways of dealing with things. He felt his handshake was not as firm as Americans’, found that people reacted unusually when he modestly insisted his English was not good after they complimented(称赞) him, didn’t know how to accept dinner invitations properly and therefore missed out on going to several lunches, and so on. Eventually, he was so confused that he felt the full impact of “culture shock”.
