Dr. Brown is always busy at work. But next month he is going to take a long vacation. He is going to China with his wife. The Browns have heard the saying, "The man who doesn't reach the Great Wall is not a true man." So they are going to Beijing, the heart of China, to visit the Great Wall.
They will stay in Beijing for about one week. They have a lot of Chinese friends there, so they will visit them. Then they will fly to Hangzhou to see the West Lake, They will go fishing there.
They plan to stay there for about half a week. Dr. Brown is always at the top of the Yellow Mountain in his dream. At last he has the chance to have a look at it. So next they are going to Anhui by train and going hiking in the great mountain. After five or six days in Anhui, they will have to go back to London and have a good rest for about a week before they go on with their work.
