How many types of evil spirits Li Juming talks about in Feng Shui and what are their differences?

Concerning the issue of evil spirits and evil spirits: From ancient times to the present, all formal Feng Shui studies never mention ghosts and gods, especially ghosts, not even a word. Feng shui only talks about evil spirits, and some people also call them divine evil spirits. Talking about evil, some people call it evil spirit. This cannot be achieved by imitating the ancients. I believe this through decades of research and investigation. 1. The so-called evil spirit: expressed in modern Chinese, it means danger and insecurity. The key to transforming evil spirits is to avoid danger and pay attention to safety. The evil spirits mentioned in all formal Feng Shui books are safety factors. 2. The so-called evil: in modern Chinese, it means bacteria and viruses. It is bacteria and viruses of unknown nature that bring illnesses of unknown nature. There is only one way to avoid evil, pay attention to hygiene. Modern research on bacteria and viruses has solved many of the mysteries of evil spirits. Bacteria and viruses are spread in many ways, but the basic modes of spread are generally: airborne spread; second, mobile spread, including the movement of people, objects, and animals; third, insect spread, which Communication is the biggest invisible killer.

What needs to be explained here is about ghosts and gods. Helplessness, incompetence, and ignorance are the only way to rely on ghosts and gods. This is a tragedy created by the ancients, and it is also a tragedy that modern superstition should be in the study and application of Feng Shui. Feng Shui and theology are two completely different things. Feng Shui is an empirical discipline, based on past successes and failures and drawing lessons from future examples. It has certain formulas and methods of use, and anyone can use them if they are familiar with and master the methods. Whether it is used right or wrong, deeply or shallowly, depends entirely on the level of Feng Shui research and the level of skill mastery and proficiency. There is no mystery; there is no need to “speak” of theology. The introduction of theology into Feng Shui, especially the introduction of theological "Hunong", has its historical reasons and the limitations of Feng Shui research. To the extent that theology is mixed with Feng Shui, it limits the development of Feng Shui.
