Last summer vacation, you traveled to Changbai Mountain and took many photos.

I went to the zoo with my friends last Sunday. It was hot and sunny that day. It took us about two hours to go there by bus. There are thousands of people in the zoo. We saw many animals, such as pandas, kangaroos, polar bears, giffy, elephants, tigers, wolves, snakes and so on. We also watched an elephant show. Elephants are very clever. They can do many things like us. At noon, we have a picnic in the zoo, and then we throw the garbage into the dustbin. We didn't go home until five in the afternoon.
