Warm reminder reminds the upstairs residents to go into battle lightly.

There are sometimes some problems in modern buildings, especially those with poor sound insulation. For example, people who live on the lower floor may sometimes be disturbed by loud music from people upstairs, or people who live upstairs walk loudly, which will also affect people who live downstairs. Then we can go to this house and knock on their door gently. Then we can tell them that I'm sorry to bother you. I live on the first floor below you. Maybe the sound insulation effect here is not particularly good. I often hear your family's voice when I am at home. I can't have a rest because I'm a little nervous, so can you walk quietly? Thank you.
