    Two hundred years ago, there were no telephones or mobile phones in China. People wrote letters to get in touch with their friends or relatives.

    Once there was an old woman, she lived alone in a village. Her son was working in the city. One night she missed her son. She could not get sleep. She wanted to write a letter to him. But she could not read or write. After some time she got up and knocked on her neighbour's door.

    “Mr. Lee, could you please write a letter to my son for me?" she asked. It was the middle of the night and Mr. Lee wanted to sleep. He didn't get up or open the door. He said loudly to the woman, I wish I could help you but I have a problem. My handwriting is very bad at night. Only I can read it. If I write the letter now, I'll have to visit your son and read the letter to him. Maybe you should come back tomorrow.”

    In Indonesia (印度尼西亚) , there is a special market. The market is on the water. Hundreds of vendors (小贩) sit in boats. They sell fruit and vegetables, for example, yellow bananas and red tomatoes. The vendors wear colourful clothes and big beautiful hats. They also decorate (装饰) their boats. All these bright colors come together. They make an amazing picture.

    Usually, vendors stay on the water for a whole day. When they go home, they go together. Look, many small boats make a chain (链子) . A bigger boat pulls them in the front. There are usually about 20 boats in each chain.
