By bus——This is the most common way. When people get on a bus, they’ll find that the bus is a little strange. It is different from the buses we often see. There are no big windows at all, but some small windows. And it looks like a cage. What are they used for? Oh, people can use it to watch animals, especially those dangerous animals ,and take photos. We know that people are most interested in the lions. So when two buses meet , the drivers will stop and ask each other whether they have found lions.
