What's the difference between Feng Juming's evil spirits?

On the issue of evil spirits: from ancient times to the present, all formal geomantic omen never talked about ghosts, especially ghosts, and did not involve a word. Feng shui only talks about evil spirits, and some people call it evil spirits. Speaking of evil, some people call it evil. This can't satisfy the ancients. I want to pass decades of research and investigation. 1, the so-called evil: expressed in modern Chinese, it means danger and insecurity. The key element of evil is to avoid danger and pay attention to safety. All the evil spirits mentioned in the regular Feng Shui books are all about the safety factor. 2. The so-called evil: in modern Chinese, it means bacteria and viruses. It is bacteria and viruses that don't know the truth, bringing diseases that don't know the truth. There is only one way to ward off evil spirits. Pay attention to hygiene. Modern research on bacteria and viruses has solved many mysteries of evil spirits. Bacteria and viruses spread in various ways, but the basic modes of transmission are generally not external: first, air transmission; The second is the diffusion of liquidity, including the movement of people, goods and livestock; The third is the spread of insects, which is the biggest invisible killer.

What needs to be explained here is about ghosts and gods. Helpless, incompetent and ignorant, we can only rely on resisting ghosts and gods, which is a tragedy created by the ancients and also a tragedy of modern superstition in the research and application of Feng Shui. Geomantic omen and theology are two completely different things. Feng Shui is an empirical discipline, which is based on past successes and failures and draws lessons from future cases. There are certain formulas and practical methods, and anyone who is familiar with and masters practical methods can use them. Whether the application is right or wrong, deep or shallow, depends entirely on the height, skill and proficiency of Feng Shui research. No mystery; There is no need to "summon" theology. The introduction of theology in geomantic omen, especially the introduction of theology "Hu Nong", has its historical reasons and limitations in geomantic omen research. To some extent, the mixing of theology and geomantic omen limits the development of geomantic omen.
