Excuse me, do you mean that the exhaust fan can't be installed on the wall of the gate? Does the property have this rule?

Simple! Pretend to be talking! Your neighbor has gone too far! Besides: the property regulations are not what you want to stipulate, and there can be a legal basis! Now some property companies have deviated from the purpose of property services! Neglect service for the so-called management! Ignoring the interests of the owners, even if it is wrong, the property should take the initiative to find a solution! Think what the owner thinks, be anxious about what the owner is anxious about, and provide services to the owner wholeheartedly!
