What are the three evils?

In the past, when people were building gardens, repairing houses and building houses, they would ask Master Yin and Yang in advance whether this place was a land of three evils and whether they could break ground. Traditionally, people often talk about the location of three evil spirits: robbery, disaster and age. Because the orientation of the three evil spirits is different every year, most ordinary people think it is mysterious, so they ask Mr. Yin Yang. In fact, the determination of the three evil spirits is very regular, which is determined according to the relationship between the earthly branch and the five elements, that is, the three directions that collide with the five elements every year. For example, in 20 13, year of the snake was the third runner-up, the third runner-up was the golden bureau, and the gold was the west. Jin Kemu, so the orientation of oriental wood, is three evil spirits. In other words, the ground branch is in the middle. Northeast, East and Southeast are three evil locations. For another example, 20 12 the Year of the Loong, the three-in-one bureau composed of Chenchen is Shenzichen Water Bureau, and the water in the five elements contains fire, so the location of the southern fire is three evil spirits, that is, the southeast, south and southwest represented by the noon branch are three evil spirits.
