School is every person's second home, so it teaches us to become good people useful to society. That's why we need to protect and develop the school. To develop our school, we need to study well, exercise well, respect teachers, participate in the school's school cleaning activities, and participate in activities proposed by the school. Reminding school members to protect a clean and green environment, organizing a day to recycle plastic wine bottles into useful ideas, organizing activities to recycle plastic into fashionable clothes. Uncle Ho said " One tree cannot make a mountain, three trees bunched together can make a high mountain." As long as we work together, the environment will become clean and beautiful, everyone's high awareness will help the school develop.
