Trinity College is one of the famous colleges of Oxford University. The college needs to buy tickets. One or two pounds a person. It's not expensive. Every time we arrive, we'll go in and have a look. The college is very big, the buildings are very beautiful, and the lawn is very big. Colleges are not entirely open to the outside world. The internal classroom library dormitory is not open. Visitors can see the facade of the college. Fortunately, I met Mr. Trinity of Trinity College. The cat is very close. It's worth seeing here.
