If you are an admirer of Mr. Holmes, the Holmes Museum at 221 Baker Street in London will be the place you must visit. This is also the former residence of Mr Holmes. In this three-and-a-half-storey building, there are still many remains of Mr. Holmes and Mr. Watson. At the same time, in different rooms, there are also some vivid figures and props in the Holmes Collection. These will bring you back to the story at that time. Walking up the third floor, you can see a bathroom. Its sanitary ware has the characteristics of blue and white porcelain. I think it's interesting. There is a queue to visit the museum. At the door, you can take a free photo with Holmes'policeman in real costume. The costumers I remember also speak authentic Chinese. He told me that he had lived near Beijing University of Finance and Economics for more than three years. The ticket for the tour is 15 pounds per person.
