According to folklore, gables are bound to hurt people. Is it true?/You don't say. /You don't say. What is the concept of gables?

Gables: generally known as external transverse walls, refers to the walls arranged along the short axis of the building called transverse walls, and the external walls at both ends of the building are generally called gables. Ancient buildings generally have gables, which are mainly used to separate from neighbors' houses and prevent fire. As the saying goes, "Gables will definitely hurt people", because the main beam of traditional houses in China is built on gables, and gables are often load-bearing walls. If the door is opened on the wall, the bearing capacity of the wall will be reduced, and the main beam is in danger of falling.
