In the first case, that is, the end of the T-shaped road, there are two unlucky factors. First, in ancient times, when the enemy attacked, such places were the most vulnerable. As far as defense is concerned, such places are often used as strongholds to stop the enemy. Another unlucky factor is that it is easily hit. When the storm hit, strong winds crossed the road between juxtaposed houses and hit the home at the end. The same is true when there is a fire, and the flame often floats to the end of the house with the wind. Because of the above unlucky factors, it is considered that the house of doom has lost face. Although there is no enemy attack in modern society, cars often hit people, so there is a "home built at the end of the road, which is a big murderer."
In the second case, the innermost part of the dead lane. There are two unlucky factors in this place. First, it is extremely inconvenient to go out and walk through other people's doors. In modern times, if the road is someone else's private land, the other person will definitely ask for or restrict you. The second is danger. If there is no other way at the end of the dead roadway, when the fire comes from the front, there is often no way out and no way out. If you must build a house here, please remember: be sure to leave a passage leading to the house at the back in advance to avoid fire.
