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.

You will swim there without danger if you remember these instructions(说明):

1. Never swim alone.

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

3. Don’t stay in the water too long.
