To be honest, it's a hard thing for you to try to dissuade them. Such a thing is not a simple individual thing, and you are not the only one to face it. Generally such things first of all or to go to the property, after all, the neighborhood is the need for a quiet living environment. Only the property is in what way to discourage, I think the excellent property company are able to deal with these things very well.
Neighbors should still live in harmony with each other, more communication, more understanding, because only good communication and understanding can be in the future, in the more permanent days of harmony. However, if you really jump square dance aunt affected you, property coordination in the case of no avail. You have to learn to adapt a little, not directly to find the square dancing aunt, but in the elevator to post your claim, with this way to remind, to prove that it is not the property in the "nothing to do", but really have the owners were affected.
If this approach is still not effective, then you still don't go directly to the square-dancing mom, see if you can put in the owners' group to talk about this kind of thing, I believe that their family members in the group, then, will be at home inside the family to remind them.
Why don't I want you to go directly to the square dancing mothers? To be honest, I'm afraid you're no match for them. Really, you must listen to people in this regard in order to have enough to eat. Don't get on the opposite side of the fence with them directly.
In fact, if you call the police to deal with such things, I'm afraid it's all very difficult to give you an ideal result. Because of the noise and nuisance are relevant regulations, they certainly will not dance in the middle of the night, so it is still up to you to deal with, how to communicate such things.
If, all the way to no effect, then there is no need for you to discourage them. The square is a public **** place, they can dance, that is, you are equally allowed to sing, jump rope, play badminton, etc., have fun! Maybe that will have an unexpected effect. If something else happens while you're playing, just call the police to deal with it.
