Ancient Feng Shui theory covers many things, including yin and yang houses, human geography, environmental changes, etc. Later generations also have mixed reviews of these Feng Shui theories.
For example, about Yangzhai, why did the ancients leave the saying "Don't plant locust trees in front, willow trees behind, and ghosts in the yard clap hands"? From the perspective of later generations, is there any scientific basis?
In fact, the meaning of this sentence is not to plant locust trees in front of the yard, not to plant willow trees behind the yard, and not to plant poplar in the yard. Poplar trees are "ghost clapping hands".
Why do you say that you don’t plant locust trees before? Because they think that locust is the ghost of wood, and locust tree is the ghost king among the trees.
Locust trees are extremely yin trees. They are easy to attract unclean things at night, such as planting in front of the yard. At night, children's eyes are too sharp and they are easily frightened.
Why does it mean that you don’t plant willows later in Feng Shui theory? Because willow branches also belong to Yin wood, and the willow branches are also filial sticks that can be dragged by filial sons for funerals, which means they are unlucky.
Also, willow trees are mostly planted against water. Water represents wealth in Feng Shui. Water can make money. Planting willow trees in front of the door means that wind and water will make money at home.
However, once planted in the back of the yard, because willow is homophonic to "liu", planting willow trees behind the house has the bad meaning of "liu money", so Feng Shui theory advises people not to plant willows behind the house.
Why do you say that poplar trees cannot be planted in the courtyard? Because the poplar tree has the title of "ghost clapping", the wind blows at night and makes a rustling sound, like a ghost clapping his hands.
This way, children will easily cause hallucinations and feel scared for no reason. Therefore, Feng Shui theory advises people not to plant poplar trees in the yard.
In fact, Feng Shui theory is not completely without scientific basis. If you insist on applying scientific basis, it is actually simple, such as why "no locust planting in front and no willow planting in the back"?
Because the root system of these two trees is too developed, the thick roots can easily destroy the courtyard wall and the foundation of the house, affecting the service life of the courtyard wall and the house.
The scientific basis of "no ghosts in the courtyard clap" can also be understood as the characteristics of poplar trees, that is, the white hair floes flying all over the sky in spring.
Some people have sensitive skin and respiratory tracts. Once they inhaled white hair floss, it has a great impact on their bodies. Moreover, white hair floss is piled up in fire. Why are they still planted in the yard for so many disadvantages?
These are Feng Shui theories, in fact, they seem irrelevant to ordinary people in modern times, and people don’t have to pay too much attention to these.
Nowadays, people live in buildings, and buildings will actually be considered by Feng Shui masters or humanities scholars, but these are not very related to those who buy houses!
