What effect will the guest sleep in the master bedroom have on the host?
In geomantic omen, the master bedroom is the owner's fixed residence, and the whole pattern and layout are related to the master's numerology, and the gas field of the master bedroom has a great relationship with the master. If outsiders come in to live, it will definitely disrupt the environment that has been in a stable gas field for a long time and affect the fortune of the whole family. Therefore, in Feng Shui, guests should not sleep in the master bedroom.
The master bedroom is a fixed place for the master to sleep, and also a private space for the master. So even if the host offers to let you sleep in the master bedroom with good intentions, you should know that it is impolite to occupy the master bedroom to sleep. Being a guest brings a lot of trouble to the host, let alone sleeping in the host's private bed. It's also a problem for others to clean up after you leave. This is the most basic polite understanding.
The host knows how to entertain guests, and you also need to know what to do and what not to do. When you go to someone's house, you'd better not sit on the master's bed. This detail is also very impolite. The host may not stop you in front of you, but he may care in private. Informal and impolite are two different things. In foreign countries, outsiders are not allowed to enter the bedroom at all.
