Sending messages in community groups can let your neighbors know about your troubles and ask for their understanding and cooperation. You can use the following expressions:
"Dear neighbors, I am a resident upstairs, and I am very sorry to disturb you. Recently, I noticed that the children upstairs often run around. This It bothers me very much. I know that children are naturally active, but I still hope to give them some space during the day and at the same time reduce the trouble for me. I have tried it with my children before. "
When posting such information, be sure to remain polite and respectful, and also express your demands. Only in this way can you gain the understanding and support of your neighbors.
