The second is to avoid facing or being too close to toilets and kitchens. Scientifically speaking, long-term oil smoke and dirty air will pollute the passage, which is also unfavorable to people in the past. From the perspective of geomantic omen, stairs are the main passage up and down, and these dirty gases will spread everywhere through the stairs.
Third, the stairs should not be built in the center of the main body of the house, and the main body of the stairs should not be too steep or too steep. On the one hand, it is not safe enough, and feng shui is also taboo.
Fourth, the entrance of the stairs should not face the bedroom. On the one hand, people go up and down, air circulates quickly, and dirt spreads quickly. Going into the bedroom is not good for your health, and your figure and voice also affect your rest. On the other hand, it is not conducive to safety and theft prevention. From the perspective of geomantic omen, complex and dynamic things have a great influence on people's mind and have a subtle influence on people's spirit.
