The zoo is the largest zoo near Washington. On the way to the zoo, we found that it should be in the mountains. The roads in the mountains are messy. It's not easy to find it without navigation. But the environment is very good. There is no ticket. But the parking time is 22 dollars, which is almost the same as the ticket collection. But there are pandas from China to the United States. There are no Chinese groups here. They are all Americans. Americans like Chinese pandas very much. American children are crazy about Chinese pandas. If you look at them, one person will buy a doll of pandas. Peer partners said that I was sick and came to the United States to see the pandas in China. I said that when the Chinese foreign minister came to the United States, he must see the foreign students. Our common people came to the United States. The spectrum is not that big. Just look at the pandas in China.
