Does the gate of the ancient house open outward or inward?

If you watch many historical plays, movies and TV in the park, you will notice that the doors of the house are all like those in the park.

As for why it may involve some feudal superstitions.

However, I personally thought for a moment that opening the door inward is beneficial to the convenience and safety of the front aisle, because "pulling in" is always more defensive than "pushing out"
