When you visit Cambridge again, the business atmosphere is much stronger. Along the way, boats are constantly promoted through various channels and at various prices. The boats on the Cambridge River are bustling like crucian carp crossing the river, which is no longer meaningful as those written by poets in the past. Although Oxford has Harry Potter Scenery as a hot spot, the old fashion still exists. Blackwell's flagship store, with its inconspicuous facade and vast and quiet sea of books, gives people a sense of vastness in the underground cave and age in the mountains. Time is in a hurry, I haven't bought a Book yet. I Miss coming back next time.
