The city centre of Manchester is not very large. It takes almost an hour to walk west from Piccadilly Railway Station to the west. It can pass through Oxford Street, Chinatown, Manchester Cathedral, Ferris Wheel and many more. Most of the buildings here are made of red brick walls, which is a feature of Manchester, and the University of Manchester is also known as the Red Brick University. Compared to modern buildings, these red brick buildings also highlight the vicissitudes of the city.
