Why pay attention to "planting fewer trees in front of the door and not opening the window behind the house"?

"Plant fewer trees in front of the house and don't open the window behind the house" is a lesson of an ancestor, and it is also based on experience, because in ancient times, people would like to plant some trees in front of their homes so that they can harvest some fruits in autumn, but because of the limited medical conditions in ancient times, planting trees in front of their homes would block the sun at that time.

Without sunshine, the house will be very damp, and there will be germs, bacteria and molds. So if people in the house stay in this environment for a long time, it is easy to get sick. Therefore, for the sake of health, the ancients warned future generations to plant fewer trees in front of the door. In fact, they mainly wanted to let the sun shine into the house, so that the house could be sterilized better and the house would be particularly warm and comfortable.

There are two reasons why there is no window at the back of the house. The first reason is that the ancients were very concerned about the theory of geomantic omen, so if they opened the back window of their home in ancient times, they would expose their wealth to other people's homes, so that their wealth would collide with other people's homes and bring a lot of trouble to their homes. Therefore, for the sake of their own harmony, the ancients warned future generations not to open the window behind the house.

There is also a saying that if there is no window at the back of the house, it can play a very good anti-theft role. If you lock up your house, thieves can't come in from behind your house, and they can also play a role in preventing theft. In fact, they are all life warnings.
