The brick lifted by Lin Mo was not only the flashpoint of the campus conflict, but also a symbol of the deviation of his life trajectory. The word "broken" not only refers to the physical bricks falling to the ground and the pages of the book being trampled to pieces, but also metaphors the collapse of the purity of boyhood and the vision for the future under the crushing force of violence and reality, with a strong sense of pain and fate. The brick was broken. The students who studied hard in the past are no longer there.
