Does the gate in Feng Shui refer to the gatehouse gate or the house gate?

This is a matter of opinion, but I would like to remind the questioner that the functions of ancient doors and modern doors are not exactly the same, so the Feng Shui theory about doors is inevitably inappropriate. For example, whether a unit building is based on the door of the building or the door of the house, it is different from the door in ancient times. In Feng Shui, the door in ancient times is a vent that receives air. This air can be felt by everyone in the house, but now the door in the unit building Can you feel the air collected by the door of the building in your house? If the door of the house is used as the criterion, can the door of the house inside the unit building absorb the air from the outside? To give a simple example, when the wind blows, the ancient houses The wind inside blows in through the door. Now the wind blows outside the building. Where does the wind inside the house blow in?
