1. Calm down first: Don't make decisions or talk in an emotional situation, relax your emotions first.
2. Communicate with each other: Both sides should sit down and listen carefully to each other's views and express their ideas to each other.
3. Find a compromise point: find a solution acceptable to both parties, so that both parties can get a fair result.
4. Seek help from a third party: If you can't solve it yourself, you can ask the counselor, the building manager or other relevant personnel for help.
5. Learn to be tolerant and understanding: There will inevitably be differences of opinion between roommates, so learn to be tolerant and understand each other.
