What is the difference between the outward opening and inward opening of the gate in geomantic omen?

In geomantic omen, "the front door of a house is the main entrance and the front door is the air inlet", which is generally beneficial to the air coming in from the entrance door, that is to say, the air coming in from the outside is beneficial to the geomantic omen of the house, but generally an airflow will be formed in the process of opening the door, so the door of the house should be opened inward, not outward. If the door is opened to the outside, it will bring a peaceful atmosphere in the house, leading to the loss of fortune and wealth.
