Our country has a vast territory, with four directions: southeast, northwest and northwest. The climate, landforms, customs, etc. are all very different. In southern cities, there is plenty of rain, and water means wealth. The more water, the more wealth you can gather. When building a house, people pay attention to "nearing mountains and rivers". Places with mountains and rivers are considered by southerners to be the ideal "feng shui treasure land".
There are many common sayings among the people, which are also divided into regions. For example, the saying I want to share today is "If you don't guard the pond in front of the house, you won't open the windows behind the house." This may not be the case in the south, but and in the north are different. So, what does this saying mean? Let’s listen to the elders’ explanations. Does it make sense?

What does "Don't guard the pond in front of the house and don't open the windows behind the house" mean?
This sentence is actually very easy to understand. It means that when building a house, it is best not to choose a location with a pond in front of the door. When building a house, windows cannot be designed at the back of the house.

1. No ponds in front of houses
In the north, there are three main reasons why it is important not to have ponds in front of houses:

1. Ponds are "dead water"
Because the north is a plain area with few mountains and less rain, so there are not many creeks and rivers flowing "living water". In order to facilitate irrigation, many people dig ponds and canals to store water for daily irrigation.
The water in the pond is basically rainwater, melted snow water, and discharged sewage. There is no "living water" that can flow. One characteristic of "stagnant water" is that it will deteriorate after being left for a long time. It slowly emits a stink and can easily breed mosquitoes and flies. In addition, bacteria and viruses are naturally indispensable.
Just imagine if there was such a "stagnant" pond at the door. When the wind blows, the odor, viruses, and bacteria are blown into the home. There are usually flies and mosquitoes flying everywhere. Who can stand it?

2. There is a safety hazard
Because there is less rain in the north, the natural amount of water is relatively small, so many people do not understand water properties. If there is a pond at the door, if you accidentally fall into it, you will probably drown.
As long as there are ponds, there may be safety hazards. If the pond is at your doorstep, this potential safety hazard is closer to your home. For the safety of your family, it is best not to have pools of water at your door.

3. The climate, environment and soil that affect the foundation
are different in each region. The land in the south is mostly red soil, which is relatively sticky. The land in the north is made of black soil, , and loess. Although the soil is fertile, it can easily fall apart if it is impacted by water.
If there is a pond at the door, it may affect the foundation of the house over time.
Therefore, there is a saying in northern : "If a pond is opened in front of the door, the family will be ruined and people will be destroyed." Judging from the geography, climate and other conditions in the north, it also makes sense.

2. “No windows at the back of the house”
Why can’t windows be opened at the back of the room? There are two main reasons:

1. To avoid cross-court drafts
Whether it is ancient or modern, when building a house, it is important to face the north and the south. A house with this orientation can keep the lower corner warm in winter and cool in summer. The reason why "no windows are opened at the back of the house" is mainly due to the winter climate.
The northwest wind and north wind mainly blow in winter, and the house faces south. The temperature in winter is cold, especially in the north, which can be described as ice and snow.
If you open a window at the back of the house, it becomes north-south ventilation. In Feng Shui, this is called " the hall wind " or "the hall is evil". Many ancient windows were made of paper and were easily damaged. The howling cold wind blows in from the window, directly taking away the temperature inside the room, making the room even colder.
Not to mention the old, weak, sick and disabled, even young adults who have been exposed to the wind for a long time are too much for their bodies.

2, folk superstition
The second statement is a folk superstition. There is a saying in the Central Plains: "There must be a kiln behind the back window of a home."Houyao means stepmother. If a window is installed at the back of the house, it means that the mistress of the house may change, so it becomes a taboo.
There is another saying that wealth comes in through the door. If a window is opened at the back of the house, wealth will be blown away through the window. The ancients believed that opening a window at the back of the house would make it difficult for the family to gather wealth, which was considered unlucky. Both of these statements are folk superstitions and are just psychological comfort.
If we follow people’s current living habits, the house should be transparent from north to south, with good lighting and ventilation. In addition, the windows are now equipped with glass, which not only ensures lighting, but also protects against cold winds in winter, so there is no need to worry about drafts.

Summary
People in every place have their own living habits. These habits are closely related to the local customs, customs, climate, and land. If you think these folk sayings make sense, you can learn from them. If it is just psychological comfort without any scientific basis, it can be completely discarded. Take the essence and discard the dross!
