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

1, there is no mulberry in front of the house and no locust behind the house.

Because of the house, most of them sit facing south.

Mulberries grow up with big leaves, which block the sun and attract insects, so they are not planted in front of the house.

Sophora japonica has thorns and climbs high. When you grow taller, you will hang the tiles on the roof when the wind blows.

2, mulberry dates and pears, do not enter the yin and yang home.

Mulberry, jujube, pear and locust trees can't be the pillars of the house. Because these kinds of trees are sweet, insects will bite, have more water and are easy to break.

There are no rich people in the house.

Apricots are slightly toxic. If apricot trees are tall and lush, they are not good for the elderly, children and weak people.

4. Planting trees in ancestral graves is for children and grandchildren, and five trees become forests and auspicious clouds.

Many people think that it is because of Feng Shui, but in fact, it is because the trees planted in the ancestral graves belong to their own families, and whoever belongs to the ancestral graves. The five trees are elm, jujube, mulberry, oak and Sophora japonica. When the son and grandson are born, they will plant trees in the ancestral grave. When sons and grandchildren grow up, they cut down trees to build houses for their wives. These five trees are just wood for four northern buildings and basic furniture.

My ancestors were horses, veterinarians and car dealers.

Besides the niche, the old carriage is ready, and when it is opened for the first time, it will be "old horse, shopkeeper and rich man". Superficially superstitious, in fact, you are afraid that someone will tamper with this important place, and an inexperienced car will destroy people.

6. Cover the gatehouse, and on the crossbeam of the gatehouse, the main family will "press" valuables, and the location is only known to the main family. Said it was to suppress the family's fortune. In fact, it is to leave a successor, the gatehouse is relatively close, the family has declined, and the house belongs to others. You can take this precious thing away from the outside.

7. Build a kitchen in the fire escape, or you will die.

The gap between the main room and the wing is called a fire escape, which is used to isolate the main room and the wing so that it will not be taken away when it catches fire. Build a kitchen in the fire escape. In case of fire, neither the main room nor the wing can run away. Building a kitchen here also shows that this family has no rules, and it is only a matter of time before they fall.

8. One entering the house is higher than two entering the house, and the slave bullies the master.

One is that the servant lives in the master's house, and the other is that the servant's house is higher than the master's house, which blocks the master's sunshine, indicating that the servant has the final say, so the slave is bullying the master!

9. Flowers with thorns can't be put in the house, but can only be planted by the wall.

It is not easy for children to play in the house. There is a thief coming by the planting wall, so it is difficult for the thief to jump down and stab first.
