     As a foreigner, I often hear the Chinese calling me "laowai". If I could not speak Chinese or if I had no

understanding of Asian customs, I might be angry when I am called a "laowai". But having lived in the

Philippines and China's Taiwan Province teaching English for several years, I have come to China with a

different view from most other foreign teachers here. In such situations, I just answer back in standard

Chinese:"Ni zenmo zhidao wo shi waiguoren? (How do you know I'm a foreigner? )" When I hear people

shout out "hello" in a more impolite way and then laugh, I reply in Chinese with "Ni de yingyu bi wo de hao.

(Your English is better than mine.)"

     Speaking Chinese is a way of living an easier life in China. As an English teacher at Hubei University in

Wuhan, I was once invited by a student to spend the weekend with his family. Because I can speak Chinese

quite freely, I was able to talk with my student's entire family. From my personal experience, I knew that the

Chinese have a "gift" for making foreigners in China feel right at home. That fun-filled weekend I spent with

my student's family in Caidian, a small suburb of Wuhan, just showed that my idea was right.

     It was an experience I will never forget.

     Americans have a saying: If you can't beat them, then join them.The secret to feeling at home with the

Chinese people isn't to try to make them change over to Western ways. The secret is to become one of them.

Just go with the flow, or don't take things too seriously. In this way you will surely feel at home in China.

     If you no longer emphasize (强调) our differences from the Chinese, you will be more willing to

concentrate on what "big noses" and "small noses" have in common.
