Mr Zhang worked at the zoo. He saw many animals asleep during the day. People did not like to see that. Mr Zhang often visited the animals at night. The animals were awake then. They ate, ran and played. Mr Zhang had an idea. Mr Zhang talked to his boss about it. People like to see the animals at night. We can have a Night Zoo. That's a great idea. Let's do it. Today, many people come to visit the Night Zoo. They like it a lot. Look! There are three elephants. This one is eating.
