It is important to note that in the past, the doors of high-status rural households, including those of royal aristocrats, would always open inwards. This is called opening the door to receive wealth, and it is like this in homes with courtyards. However, for large public places, especially closed places such as churches and synagogues, the doors should open outward to facilitate fire escape.
Strictly speaking, the doors of ordinary residents in urban buildings should also open outward to prevent fire. However, in situations where the space is small, opening the door inward is a helpless choice. However, opening the door inward can indeed confirm the Feng Shui habit of receiving wealth.
