What about the geomantic omen of a house surrounded by mountains on three sides?
Generally speaking, there should be no river crossing in front of the house, no old buildings, no lakes behind the house, and the door should not face the road coming straight. The direction of the house should be positive, that is, the door should either face due east or south. The most important thing is that the door must not face the nearby mountain. It doesn't matter if it is far away, as long as it doesn't block the view of the house.
Whether the house is good or not is not the most important thing. You should look farther and look at the big feng shui. What is great geomancy? It is actually a subjective consciousness of people. To put it bluntly, that is to say, as long as the house looks pleasing to the eye at first glance, everything else is trivial. If there are taboos, it can also be adjusted through architectural style, orientation, courtyard layout, room decoration, etc., and finally achieve harmony between man and nature.
