In ancient China, there would be thresholds on the gates of every house, especially in ancient palaces and palaces, and great attention was paid to the decoration of thresholds. In modern residential feng shui, the threshold plays a very important role, if the threshold is used incorrectly, then it will directly affect the entire feng shui layout of the residence, let's talk about the problem of threshold feng shui in detail. The threshold has a very important meaning in Feng Shui, and its role is to block external adverse factors from entering the home and prevent the leakage of wealth. The threshold has the effect of gathering wealth, so the threshold of the door is indispensable when decorating the home. There is a folk legend that the threshold is the owner's back or the cervical vertebrae of the neck, and people are not allowed to step on the threshold. 
Good day and auspicious day to install the threshold, I wish Mr. Zhu a prosperous business, prosperity, good luck, peace and health, and good luck!
The feng shui meaning of the threshold looks very inconspicuous in home feng shui, but it is a link that cannot be ignored, which is the threshold. In China, there is a threshold at the entrance of traditional houses, so that even if the door is open, there is still a "checkpoint" invisibly, so Feng Shui calls the threshold "guanlan". But about the value of the threshold in feng shui, I am afraid that not many people know much.
1. Because there will be a gap between the door and the ground, and it is precisely because of the existence of this gap that it will affect the aura of the entire residence, so that the aura will flow out and disperse from this gap. If a threshold is placed to block this gap, the aura of the house will be gathered. 2. The principle of gathering wealth and gathering wealth is the same, after setting the threshold, you can prevent the loss of wealth from the crack in the door, and gathering gas and gathering wealth are actually connected. 
3. Setting a threshold to block the yin wind can not only ensure that the wealth and gas inside do not flow out, but also prevent the outside wind from coming in. Set a threshold to block the gap under the gate, so that the wind does not come in from under the gate. 4. In feng shui, it is not only important to set the threshold, but also to set the best steps. This will prevent the entry of lonely ghosts. Legend has it that lonely spirits and wild ghosts jump upwards with both feet at the same time, and if the steps or thresholds are too low, they will jump directly into the house. 5. The threshold can reduce the "air rush" Speaking of the usefulness of the threshold, a large part of it is related to feng shui. Among them, the clearest one is that the threshold is like a dividing line, separating the "small Qiankun" of the residential house from the entire "big Qiankun" of the outdoors. When people come in and out, they will bring up a faster air current, which is called "qi chong" in feng shui, and rushing directly into the house will be detrimental to the family. However, if there is a threshold under the door, you have to step over it when entering and exiting, which can play a role in easing the pace and greatly weakening the "air rush". "6. Gather popularity, benefit the health of women in the family, and prosper people. 
Pay attention to the threshold: 1. Some people believe that the threshold has a special symbol, it is the head of the family and the neck of the ancestors, once the threshold is stepped on, it is disrespectful to them and violates the rules of the ancestors. In some areas, people have a variety of door gods in their homes, they worship them as protective gods, and the threshold is the barrier of the gods, if you step on the threshold, it will break your own feng shui, and collide with the family god. 2. The threshold has the function of shielding dirt and avoiding evil, and a threshold is placed horizontally at the door, symbolizing the erection of a wall to block all bad things, especially those ghosts and monsters, in order to ensure the safety and happiness of the family. 3. There is also a saying that the threshold is the neck of the family and the head and neck of the family, so there is a saying: do not step on the threshold and do not sit on the bucket. 4. Legend has it that stepping on the threshold will damage your own feng shui and collide with the family god (in some regional folklore, it is believed that each family has a protective god). The custom of avoiding stepping on the threshold continued until the Qing Dynasty. 5. The reason for gathering wealth and gathering is the same, after setting the threshold, you can prevent the loss of wealth from the cracks in the door, and gathering qi and gathering wealth are actually the same. A mansion with an aura that does not gather wealth is also not gathered, and wealth comes and goes!
