1, report to the relevant departments of the school: report the problem to the student union, the academic affairs office or the sports department, and seriously explain the hope that the school can build a gymnasium.
2. Organize signature activities: launch a petition in the school and invite more students to participate to show the strong demand for building a gym. Signature activities can also help more people understand the problem and increase their influence.
3. Give advice to the school: Write a formal letter of advice and submit it to the school leaders to explain your thoughts and suggestions. The proposal should include detailed plans and suggestions, as well as your own specific requirements.
