This kind of thing cannot be explained clearly. If the background is fierce enough, of course, you can suppress them and make them pay the price, or you can only admit it yourself.
My friend was robbed of a notebook two days ago, and finally he had to admit it.
Of course, the community you live in has to pay security fees and property management fees every month. It is the responsibility of the security company to find the community management Committee.
If the railing of the construction party affects the safety of the community, the security company will raise it first. If they don't say anything, either they have reached some kind of agreement, or the security management of the security company is not in place and they have paid the security property management fee, so they must be responsible in this regard.
