First, pay attention to the ventilation of toilet.
Second, the toilet should be cleaned several times a day to be clean, tasteless and urine-free, and the floor and walls of the toilet should also be paid attention to. If it is dirty, clean it up quickly.
Third, put a piece of crystal in the toilet, which has the effect of eliminating yin and purifying. If you can't find or buy it, you can put bamboo charcoal instead of crystal in the toilet.
Fourth, try to choose brighter lamps in the bathroom. Red ornaments can be hung on the toilet door, not too expensive, such as blessing characters and paper cutting.
