There are three treasures on the ground. Why is it fire, water and wind, but not others?

Three treasures in the sky, three treasures in the sun, moon and stars, three treasures in feng shui and fire. Why not something else? According to traditional Chinese medicine, the four elements that make up the world are those who have lost sperm, death, death, absence, death, fire, water and wind. If people have no spirit, they are no longer perfect. Without fire, water and wind, the world would no longer be a perfect world. If there were no sun, moon and stars, it would be dark.
