     Kunming is the capital of Yunnan. It's a city with a long history. Kunming has a population of more

than 5,000,000. Though the weather in Yunnan changes from place to place, Kunming is famous for her

beautiful weather. It's neither too hot in summer nor too cold in winter. That's why more and more people

like to travel and even to live here. You can see that great changes have taken place here. A lot of tall

buildings, cinemas and hospitals have been put up. You can cross the streets over footbridges in the

city. You can buy whatever you want in shops and supermarkets in or around the city. People's lives are

becoming better and better.

     At weekend or on holiday, people like to relax themselves in different places and in different ways. In

winter, people, especially old people, would like to climb the Western Hills. From the top of the Hills,

you can have a good look at the beautiful scenery of Kunming. Far away from the Hills, you can enjoy

the Sleeping Beauty among the Hills. After supper, families take a walk along the bank of Dianchi Lake.

city.  EXPO Garden is known to people both at home and abroad. You can spend a whole day visiting

the world-famous garden. A little farther away from the southeast of the city, a special forest welcomes
