Read more books. Read some extra-curricular books, such as books on humanities and social sciences, books on historical philosophy, sort out the ups and downs of past dynasties, and understand the honor and disgrace of tasks of past dynasties. Reading is undoubtedly the most direct means to calm down and broaden your horizons, because reading itself is to accept knowledge, see the outside world and see the author's thoughts. However, at present, we are facing many pressures. As a student, it is difficult to let go completely. Therefore, this is a very difficult thing to do. In addition, the practical method is to make friends and enjoy communication by passing ideas and information to each other, so as to broaden your horizons and increase your knowledge.
