判断句子的正误。

One day, Tom tells his friends, "I'm going to have holidays in Beijing. But I can't speak Chinese, so I'm going to have evening classes and have Chinese lessons there for a month." Soon his holidays come and he goes to Beijing happily. After he comes back, his friends ask him, "Do you have any trouble(麻烦) with your Chinese when you are in Beijing, Tom? "No, I don't." answers Tom "But the Chinese do! They can't understand me."
