Plant fewer trees in front of the door.
Presumably, in everyone's impression, planting trees should be a matter of beautifying the environment and refreshing the air. What's wrong with enjoying the cool on a hot day? Moreover, fruit trees will be planted in many places in rural areas, and fruits will be harvested in autumn and summer. But why did the ancients say "fewer trees are planted in front of the door"?
In fact, the reason is very simple. First of all, ancient medical technology was underdeveloped and always paid special attention to health and health preservation. Although there are many benefits of planting trees, the disadvantages are unbearable. As we all know, if there are many trees in front of the door, it will naturally block the sun, resulting in humid and even moldy indoor environment. People get sick easily in such an environment.
Moreover, there were no brick houses in ancient times, mostly wooden houses, wrapped in plain soil. Being in a humid environment for a long time without sunlight is prone to cracks, which greatly shortens the life of the house. That's why there is this warning that "fewer trees are planted in front of the door".
Don't open the window behind the house.
Perhaps many people are even more confused about this sentence. Why can't we start at the back of the house? Is there a problem? Why didn't the ancients let the window open?
In fact, this has two meanings. One is Feng Shui. As we all know, the ancients paid special attention to Feng Shui, from royalty to ordinary people. Although ordinary people can't be like members of the royal family, the whole Forbidden City is arranged in strict accordance with Feng Shui, but ordinary people also have their own unique views in life.
First of all, if the back door opens a window, it is facing someone else's door. The ancients paid attention to "the door makes money, and the window makes money." If the window is facing the neighbor's door, the other party will naturally feel rich. It is very likely that you will find trouble, and even if you don't say it, you will accumulate unnecessary contradictions.
On that day, there was another view that if the rear window was often opened, it would be easy to attract thieves. The ancient windows were all made of wood. If the window is opened and targeted by thieves, it will be easy to pry it open. With the windows closed, the thief doesn't know whether the master is at home or not, so naturally he can't expect too much.
These two proverbs are also very useful in modern times. When we talk about life, we often mix some cultures at that time, such as Feng Shui and folk customs. However, two simple sentences seem to tell all aspects of life.
