(2) Planting trees to improve the road environment. Human life is always inseparable from the plant environment. Modern urbanization makes people far away from the land, making people feel suspended in the air and have no sense of stability. The area of plants is getting less and less, and man is like a lonely animal without support. The same is true of residential buildings. The premise of the same breath is that there are more than two things, so the house must be in a certain plant environment, especially they provide us with food sources such as nourishing qi, which is also changing our relationship with nature. The general principle of planting trees in geomantic omen is comfort, which can reduce the noise and chaos from the main roads and give people a quiet environment, but not too many trees; If you can't plant big trees in front of the gate, because big trees not only block the sun from entering the house; At the same time, the yin in the house is not easy to get rid of.
In this choice, Feng Shui believes that peach willows (Yima) will be planted in the east, gardenia elm will be planted in the west, plum dates (Niu Yi) will be planted in the south and apricot trees will be planted in the north. And "a tree in the middle door, three generations of wealth, an elm tree behind the house is not close to ghosts", "apricot in the east of the house, plum in the north of the house, and peach in the west of the house are all lewd", "double dates planted in front of the door, green bamboo and wood on all sides, are bound to produce wealth" (volume 4 of Xiangzhai Classic) and so on.
