It is a landmark building in the City of London. All the buildings in the City are modern office buildings, which are symbiotic with the sense of history and culture of the Old City of London. The city is mostly white-collar workers. The elites in suits and leather shoes are often seen smoking on the roadside, and cigarette ends are everywhere on both sides of the road. It seems that the elite also have uncivilized behavior, just for the sake of not breaking the law, they will go downstairs and solve it outdoors.
