The basic concept of villa is negative yin and yang, which is equivalent to the water behind the mountain (mountain yin and water yang), that is, it inclines from high to low.
In urban construction, the road is virtual water and the biggest sun, so it is not necessarily underestimated by Gao Chao. So the ups and downs of the Eight Palaces become complicated. Modern commercial houses, I-shaped houses and diamond-shaped houses have strange shapes, which make the ups and downs of eight rooms more complicated.
Around 2000, there was a Su Minfeng Feng Shui master who advocated directly using the ups and downs of the entrance door. Some people object and advocate using the biggest balcony or the biggest window as the orientation.
In fact, it is the struggle between the house and the door. Sometimes the house direction is the door direction, and sometimes the house direction is not the door direction. The eighth house should face the house.
The house is high in the north and low in the south, and the entrance is due east. Upper north and lower south is a general concept. If there is a balcony facing south, it should still be a bungalow. If there is no balcony or big window facing south, it should be used to change rooms.
