What "superstitions" may seem ridiculous, but actually have scientific basis?

What "superstitions" may seem absurd, but actually have scientific basis?

1. Do not plant mulberry trees in front of the house or plant locust trees behind the house.

Because most houses face north and south.

When the mulberry tree grows up, its leaves will become large, block the sun, and attract insects, so they should not be planted in front of the house.

The locust tree has thorns and can climb high. When it grows taller, the roof tiles will fall off when the wind blows.

2. Mulberry, jujube, pear and sophora will not enter the yin and yang house.

Mulberry, jujube, durian, pear, and locust trees cannot be used as beams or pillars in the house. Because these types of trees have a sweet taste, are easy to be bitten by insects, have a lot of moisture, and are prone to cracking and damage.

3. Apricots are flourishing in the house and people are not prospering

Apricots are slightly toxins. If the apricot trees are tall and lush, they will be bad for the elderly, children and people with weak health.

4. Plant trees in ancestral graves for children and grandchildren, and five trees will become a forest and auspicious clouds will come.

Many people think that it is because of Feng Shui, but it is actually because the trees planted in ancestral graves belong to their own family, and whose ancestral grave belongs to whom. The five trees are elm, jujube, mulberry, oak, and locust. When sons and grandsons are born, trees are planted in the ancestral graves. When the sons and grandsons grow up, the trees are cut down to build houses for them to marry. Five trees are just enough wood for the construction of four north rooms and basic furniture.

5. My family’s ancestors were in the business of horse breeding, veterinary medicine, and car dealers.

To talk about something niche, in the past, once the carriage was ready, the first time it was driven out, it had to be "old horse, shopkeeper, and big boss". On the surface, it was superstitious, but in fact, it was because of fear of key points such as the shaft. Someone did something wrong, and an inexperienced car crashed and injured someone.

6. When building the gatehouse and going up to the beams of the gatehouse, the owner of the house should "press down" the valuables, and only the owner knows the location. It is said that it suppresses the family's fortune. In fact, it is a backup plan. The gatehouse is easier to access. If the family falls into decline and the house belongs to someone else, this "precious" thing can be taken away from the outside.

7. If you build a kitchen in a fire tunnel, you will either die or die.

The empty space between the main room and the wing rooms is called the fire path, and its purpose is to isolate the main room and the wing rooms so that they will not be ignited in the event of a fire. Build a kitchen in the fire tunnel. If it catches fire, neither the main room nor the side rooms can escape. Setting up a kitchen here also shows that this family has no rules, and they only care about their heads and not their butts, so they will fall sooner or later.

8. The house on the first floor is higher than the house on the second floor, and the slave is bullying the master

The servants on the first floor live, and the master’s house on the second floor. The servant’s house is higher than the master’s house. It is so high that it blocks the master's sunlight, which means that the servant has the final say as the steward, so he is bullying the master!

9. Thorny flowers cannot be placed in the house, but can only be planted near the wall.

It’s hard to get stuck when playing in a child’s room. There is a thief coming near the wall. The thief jumps down and pricks him first.
