The toilet is not a clean place, so it should not be placed in auspicious positions, such as the angry position. However, it must be placed in a critical position to suppress it and achieve the effect of fighting poison with poison, so that it is not bad but good. Secondly, the toilet should not be placed in the center of the house, because the middle of the house is the heart of the house and is extremely important. If the center is polluted, it will be unfavorable to the entire house and unsightly; the toilet should not be opened in the southwest or northeast, because the main focus of the toilet is water and water supply. To remove water, the water vapor is very heavy. If the toilet is opened in the southwest or northeast, where the qi is strong, there will be a problem of "earth suppressing water", which is unlucky, especially the health of the family will be damaged; the toilet should not be opened in front of it. Square, because the "fire" in the south is strong, it is incompatible with the toilet in the "water", so it is unlucky.
