dear jenny,
thank you for your e-mail. i’m glad to hear that you are interested in china and i will be happy to try to tell you something about my country.
china and the usa are both large countries. some things about the two countries are similar, while other things are different.
the two countries are about the same size, but china is a little larger with an area of 9.6 million km2. however, the population of china is many times larger. it has a population of nearly 1.3 billion but the usa has only about 283 million. this means that there is much more space in the usa for its population.
two of the most important cities in the usa are on the east coast. they are new york, the largest city in the usa, and washington dc, the capital. los angeles is the largest and most famous city in the west coast. in china there are many cities with large populations. among the best known are beijing, the capital, tianjin, chongqing and shanghai, the largest city in china.
i hope this will help you. if you want to know more about china, or about me, please send another e-mail. i would be happy to hear from you and i would like to know more about the usa.
yours,
