Using the wall clock that is always three minutes early at the back door of the classroom as the coordinate axis, the stories of all the members of Class 9 [10] were bound into a book page by page. From the fragments of the novel circulated under the desk, to the unexpected rainbow at the end of the sports meeting; from the note confiscated by the class teacher, to the starlight at the end of the corridor on the eve of the high school entrance examination. This record book not only preserves the speed at which chalk dust falls, but also seals the secrets that no one ever revealed.
Purpose: Record youth
