Hong Kong has about forty public beaches. Some of the beaches are among the best in the world. People can go there for a swim. You can go to most of them by bus. To go to some beaches you must take a boat. There are toilets, changing rooms and places to buy food and drink on most of the beaches.

    You can swim there without danger if you remember these notes:

    Never swim alone. Never swim after a meal or when you feel hungry or tired.

    Do not stay in the water for too long.

    Never go out from a boat if you cannot swim.

    Remember: A red flag means that it is dangerous for anybody to go into the water. A blue flag means that it is dangerous for children.

    I am Ken. Three years ago, I a beautiful stamp on an envelope. The letter was from my father's friend. I loved the stamp very much. My father let me keep it and that was the first stamp I had. Now I have two hundred stamps. I always go to the post office to buy stamps at the weekend. Sometimes I use my pocket money to buy some stamps, but I can't buy the most ones. They are very dear. Now I have 10 . It is just enough to buy a new with a panda. So I get ready to go to the post office near my house.
