How does the eight-character evil affect fate?

It is said that there are hundreds of kinds of evil spirits. Those who represent good luck are called auspicious gods and those who represent bad luck are called evil gods. There are many kinds of good luck and evil spirits, which represent certain aspects of life that should be good or bad. But in some cases, evil spirits can also bring good luck and good spirits can also bring bad luck. For example, the fierce spirit of the sheep blade mainly represents the disaster of mass annihilation, but if the fate of the Lord is weak, the yang blade can help the body, but it is auspicious. Auspicious gods are forbidden to be punished, but the punishment is fierce, and evil spirits may turn into good luck. From this point of view, these gods are just synonymous with the ten gods (shoulder-to-shoulder, robbing wealth, eating god, hurting officials, being rich, being partial to wealth, being partial to officials, being partial to officials, being partial to printing, being partial to printing) attacked by the Five Elements Theory. It is difficult for people with complex system, shallow culture and poor understanding to really get started. So some experts, based on their long-term practical experience, summed up some laws that haven't changed much, and each law has changed its name, so that some people with shallow culture and poor understanding can use it. These names are the so-called ghosts. Folk warlocks describe these monsters as mysterious and even demonize them to scare people and improve their deterrence. In fact, they are just a name, representing a certain law of fate. Generally speaking, the theory of five elements of life does not use magic evil, but it also combines two aspects, which is very convenient to express. Especially some common evil spirits, such as peach blossom, post horse, canopy, sun blade, lonely morning and lonely night, will be used in combination when we die. These four monsters are the most commonly used and accurate. The basic meaning is: peach blossoms represent the fate of the opposite sex and are easy to get lucky; Post-horse represents a long journey or migration; Gai Hua represents loneliness, faith and the pursuit of mysterious culture; What the male blade represents has been said before, so I won't go into details here; Being alone in the morning means that the marriage is not going well.
