How do men and menstruating women share bad luck with feng shui?

Take a bowl of clean water, be sure to clean it. The tap water is not good. Put the clean water on the bed and put a small piece of charcoal in the bowl for a week. No one can touch the bowl for a week. After a week, I poured out the clear water, dried the charcoal and burned it. This is the simplest and easiest way. There are some immoral methods. You can use this first, not anything else.
