Casually wandering around London, on a small road, saw several magnificent high-rise buildings, and saw two new buildings, and a few years ago, one of which had two tall statues at the door, which appeared solemn, thinking that the courts, procuratorates and other government organs, Check out the third-ranked Imperial University of Technology in Britain, founded in 1907, to calculate that these old buildings have been 100 years old, still look majestic, magnificent, no signs of decay, the school has no walls and gates, outsiders can enter and exit at will, Of course, you can't enter the classroom to affect teaching. The fog can take pictures freely outside, see the young people shuttle through it, feel the atmosphere of the university, and be satisfied.
