Some big inspirational words or national flags can be posted on the blackboard, and notice boards, class schedules, seating charts and so on can be posted beside the blackboard. If there is a classmate in your class who will learn to write calligraphy, ask him to write some couplets or slogans and stick them on both sides, which is quite imposing. If not, put up some beautiful pictures, or decorate yourself with paper crane and stars. You can also put up some appraisal columns to see who has more apples. Post handwritten newspapers, homework display columns, knowledge training columns, etc. at the back of the classroom to decorate it beautifully. You can put some big stickers or window grilles on the windows. If not, ask the art teacher to draw some sketches. I am a sixth-grade student, and there are classmates' paintings on both sides in the classroom of our class. Reading is not very beautiful but very beautiful and comfortable.
