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.

4. Hello, dear neighbor: I don't know which family bought a new home theater and surround sound in this unit. Although this has realized your dream of watching movies at home, as your neighbor, I can be disturbed by you almost every day. And every weekend, you seem to invite friends to watch it until the early hours of the morning. Your home theater is really high. Your tape is in an exciting place, even my glass will tremble. I hope you can realize the seriousness of the problem and correct it as soon as possible, otherwise we may take other measures next time.

5. Hello, I have met my neighbor, but I don't know his name. Recently, you have brought me too much noise, not only the sound of walking around in high heels, but also the sound of dragging on the ground, playing the erhu and even having a party, which has seriously affected my life. I am worried every day because of the noise you make. I wonder if it can be settled peacefully. After all, we are civilized people. Can you turn down the volume? Thank you.

6. A letter to the neighbor on the third floor of Unit 4 in Building 7: I have been struggling for a long time, so I decided to write this letter to you. I don't know when your family will play cards until late at night (sometimes all night) every night. Mahjong is very loud. I'm really sorry, this kind of entertainment is more or less unbearable for us. I hope you don't base your happiness on our pain. Thank you.
