Geomantic omen: Why can't we use the old bed?

feng shui style: why can't I use the old bed? -From the folk custom, it is just a custom taboo that the old bed can't be used, and it is a regret based on some unpleasant cases caused by some special cases. Modern scientific analysis is "residual hazardous substances". On October 3th, 216, at 21:39, CCTV's "Challenge Impossible" police dog grass root blood search program, after a drop of blood is diluted to hundreds of billions of times, samples containing blood factors can be selected from it, which shows that "residual harmful hazardous substances" cannot be completely eliminated under the general treatment, so there are bound to be hidden dangers, which is also a powerful fact to scientifically explain the phenomenon that old beds cannot be used.

On the issue of supernatural evil spirits and evil spirits in geomantic omen:

From ancient times to the present, all formal geomantic omen never talks about ghosts, especially ghosts, and does not involve a word. Feng shui only talks about evil spirits, and some people also call it evil spirits. Talking about evil, some people call it evil. This can't satisfy the ancients, I think through decades of research and investigation. 1. The so-called evil spirit: expressed in modern Chinese, it means danger and insecurity. The key elements of evil spirit are to avoid danger and pay attention to safety. The evil spirit mentioned in all regular Feng Shui books is the problem of safety factors. 2. The so-called evil: in modern Chinese, it means bacteria and viruses. It's 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 a variety of ways, but the basic modes of transmission are generally not external: first, air transmission; Second, the spread of mobility, including the flow of people, goods and animals; The third is the spread of insects and microorganisms, which is the biggest invisible killer.
