Does the opening of fresh air exterior wall require property registration?

Need. Fresh air system refers to a series of technologies that introduce indoor fresh air into areas that need fresh air, such as bedrooms and living rooms, and exhaust indoor dirty air to the outside. To build a new wind system, the opening of the external wall should be reported to the property. The word property is translated from English property or estate, and introduced into coastal areas and inland areas from Hong Kong, meaning property, assets, real estate, real estate, industry and so on.
