1, Mr xxx: Hello, I am your downstairs resident. In recent days, after 10 in the evening, your house always makes inexplicable noise, which seriously affects the downstairs residents and causes our children and the elderly to lose sleep every night. I hope you can correct this warning letter as soon as possible. Thank you.

2. Hello neighbor xxx. Can you stop skipping rope in the bedroom? Every time you jump rope upstairs, the ceiling of our house will tremble, which seriously affects our sleep. I hope you don't exercise in your room at 7 am. You can go to the fitness equipment downstairs to exercise, which is good for everyone. Finally, I wish you a happy mood and hope you can correct it as soon as possible. Very troublesome.

3. Hello, residents on the fifth or fourth floor. Almost every night, tables and chairs are moved, and from time to time, objects fall to the floor from a height. Why? If it is cleaning, can it be changed to daytime? Our building is an old building, and the sound insulation is not very good. What's the matter with you? I hope you will correct it as soon as possible after receiving this letter, and don't continue to affect the residents of this building. Thank you.
