     You may know the English letters A, B and C. But do you know there are people called ABC? You
may like eating bananas. But do you know there is such a thing a "banana person"? How strange! Are
these people from "another earth"? No, they are just Chinese people like you and me.
     ABC means American-born Chinese. An ABC is a Chinese,but was born in the United States. Sometimes,
people call an ABC a "banana person". A banana is yellow outside and white inside-looking like a Westerner
and yellow outside - looking like a Chinese.
     Do you know why? Usually, ABCs know little about China or the Chinese language. Some of them
don't speak Chinese. Also, they are not interested in Chinese politics.
     But if ABCs can not speak Chinese, can we still call them Chinese people? Yes, of course. They are
Chinese. They are overseas Chinese. These people may be citizens (公民) of another country like the US,
Canada or Singapore. But they have Chinese blood. Their parents, grandparents or even great-grandparents
were from China. They all have black eyes and black hair. But they are not Chinese citizens. They are not
people of the People's Republic of China. For example, we all know the famous scientist C.N.Yang (杨振宁).
He got the Nobel Prize for Physics in 1957. Chinese people love him. But he is an American citizen.
