In China, many people are leaving the countryside to find jobs in the cities, because the countryside is much poorer than the city, and often there isn't much work there. Services such as hospital and transport （交通） are usually much better in the city than in the countryside. They hope that their lives will improve when they move to the city.

    But in the big cities of Europe like London or Pads, people are moving out of the city. These rich families want to live a quieter life. They are tired of the noise and the dirt （尘土） of the city, and they are tired of the crowded streets, crowded trains and buses. They don't want to live in the cities any more. They want a house with a garden in the countryside, and breathe the fresh air there.

    So they move out of the cities. Some don't go very far, just a little way out of the city, to the towns near the cities, other people move to the real countryside with sheep, cows and green fields. There, they start new lives and try to make new friends.

    Not all those who move from the city to the countryside are happy. After two or three years, many people who have done this feel that it was a big mistake. They don't make so much money and there isn't much work to do. People in the countryside are very different and aren't always very friendly.

     As a result, quite a lot of people who have moved to the countryside move back to the city. "It's wonderful to see crowds in the streets and cinema lights," they say.
