Environmental psychology terms explain the principles of hope and shelter.

Prospect-shelter theory: people always appear as "hunters" and "prey" in the process of landscape aesthetics. As a "hunter", he needs to see others; As a prey, he doesn't want others to see him. Humans like places where they can look out without being discovered, so that people can see their prey, but they will not be discovered by the enemy. Therefore, human beings should not like the environment with extremely high or low openness. From the perspective of geomantic omen, close to the mountain, with the back of the mountain and the back of the water, you can have a lookout, a shelter, a sense of security and a broad vision.
