Reader Chen: Before answering this question, first of all, thank you for your support. In geomantic omen, we attach great importance to the master bedroom, because it is the main gas field concentration of the house. We are creatures, and all creatures need to breathe. In the physiological action of breathing and inhaling, what Feng Shui experts call "Qi" is formed. There are two reasons why the bedroom door should not face the door: the airflow between the door and the bedroom door is a place with high privacy. Let's look at the first question first. Most friends who have listened to Feng Shui teachers have asked the word "Chong". There are two kinds of qi mentioned in Feng Shui, one is the terrestrial qi, and the other is the good or bad luck of flying stars. The gas enters mainly through doors and windows, and the gas at the door comes from the outside. And the hall should be a place to gather gas. This concept, we immediately understand that qi comes out of the gate. If we can't get together in the hall, the consequence will be that the house will be defeated. In order to reduce the ferocity, we suggest hiding a feng shui copper ruler or even five emperors' money at the threshold of the gate, which can use the power of the five elements to condense qi.
