Oh, it was cleaned up on a large scale this year, and books can be borrowed from the seventh grade. Its opening time should be around 9 am and closing time should be 6: 30. You can't get there at 6: 30. If you arrive around 6: 20, it seems that the waiter won't let you in. And it seems that they didn't open the museum on Friday afternoon, and there are quite a lot of books in it!
