_ Classic Feng Shui named it Shang Sha, or T-Junction Sha. A house facing T-Junction or three-way intersection was widely known as bad fengshui that many Masters in the past advised their customers try to avoid it.
_ Firstly, we need to analyze why it is called bad Feng Shui? 3-way intersection was seen as an air channel which increase wind speed. Qi (a term in Chinese FengShui indicating invisible energy that affects our lives) is transported by moving vehicles on road such as cars, motorbikes, pedestrians, etc directly and violently to facing of the house. In case Qi is too much complicated to grasp, you can visualize how it feels like standing at a house facing T-Junction in just a few minutes. You would breathe in all polluted air, dirt conveyed straight to you. To understand this clearly, just recall how vacuum cleaner works with the long pipeline like the leg of T and the mouth of you/your house (Qi Kou) opens to admit dirty polluted air.
Due to high speed of direct and violent wind, you will feel a little bit dizzy just like the way you feel sitting close to a fan for a long time.
T-Junction Sha is even worse if you put it in Vietnam heavy traffic environment. Truck drivers tend to drive as fast as they can to avoid traffic jam causing high probability of traffic accidents to your house. Or truck driver may get asleep or drunk while driving. You will hardly get a sound sleep as windows being flashed through all night.
As principle of Qi distribution shows, if the cross section of pipeline is very small and the length is very long, then the intensity of Qi is so much forceful. Remember the last time you water your garden, in order to have a forceful flow of water, all you have to do is squeeze the plastic pipe. The smaller cross section of plastic pipe is, the more forceful the water flows. Thus, the longer length of the pipelines, the smaller of cross section; the higher wind speed flows to our house.
Then, is it clear enough to come to conclusion that 3-way intersection is very BAD Feng Shui?
After all, house facing T-Junction is a bad accommodation as people living in it will breathe in polluted air, eat dirty food, feel worried, uncomfortable (due to living in unconscious fear of traffic accident).
Feng Shui Cure: Once you understood why it is considered Bad Feng Shui, you can figure it cures by yourself. To avoid dirt winded to home, you have to plant trees as air filter. The ideal trees here are coconut trees since you want to slow down wind speed for its hard leaves. For the interior part, you can use room divider at the living room for changing violent Sha Qi into slow, soft Sheng Qi. For avoid windows being flashed all night, you can use thick curtains.
Many Masters requests clients to use Ba Gua Mirror to cure this bad Feng Shui as they argue that Sha Qi is like “bad poisonous arrow straight to home”. But as we have analyzed above, the main reasons are the dirt, high wind speed: you can’t handle that with just a small mirror. Mirror is for driving Qi, not for slowing down wind or filtering air.
However, all these analysis above are under Landform & Eight Mansion Perspective only. To decide whether a T-Junction bad or good fengshui, you must be able to analyze if the Qi is good or bad energy. In fact, air-channel was just the way to increase wind speed to come to the building faster. If that direction does not have good energy, the air-channel will bring a very strong bad energy. On the other hand, the extreme good energy will be brought to the building if is in the positive direction. That will result in the prosperity, which could turn over your life almost at once. However, the opportunity to meet the lucky air-channel is very rare. It is just only two out of eight chances. This is the reason why most of the masters in the past always recommend people to avoid the air-channel or three-ways intersection for the safety purpose.
And you can only realize whether Qi good or bad by using San Yuan theory system.
