Iron pot feng shui under the bed.

People spend most of the day in bed, so this is very important. Geomantic omen pays attention to the fact that after people fall asleep at night, they are negative, receiving the local atmosphere, the weather is positive, and the local atmosphere is negative. The combination of yin and yang is the method of geomantic omen. Therefore, the bed should be clean, and no sundries should be placed to block the intake passage.
