Fengshui alum

Alum doesn't play much role in feng shui. It is just an ordinary chemical substance, which can be used to purify water, disinfect and sterilize. However, alum also has some taboos in geomantic omen, such as not to put it directly at home or at the bedside.

As for the role of alum in geomantic omen, there is no scientific basis, and it is impossible to judge whether it is a lump or a powder. However, in geomantic omen, the use of alum needs to pay attention to the following points:

1. Can't be put at home directly: Alum is a chemical. If you put it directly at home, it may have an impact on human health and need to be properly kept.

2. You can't put it on the bedside: Alum is a cold thing in Feng Shui. If it is placed at the bedside, it may have an impact on people's health and needs to be properly kept.

3. Can't put it in the kitchen: Alum belongs to fire in geomantic omen. If put in the kitchen, it may affect people's health and need to be properly kept.

4. Can't put it in the bathroom: Alum is a cold thing in Feng Shui. If it is put in the bathroom, it may have an impact on people's health and needs to be properly kept.

In short, alum does not play much role in geomantic omen, but attention should be paid to the matters needing attention when using it, so as not to affect human health.
