Why choose a house facing south?

Remember that song? The sun is shining! That's what Sichuan said. We don't see the sun for a few days a year, and when the sun comes out, we have to beat gongs and drums. Since there is no sun most days, the orientation of the house is not so important, so there are houses facing southeast and northwest. But in most other areas, most of them face south, and the price coefficient in other directions is much lower and no one likes it. So if you fall in the city, please refer to the direction of the balcony to find the south, except Sichuan! ! Ha ha. However, in fact, in rural areas, it is ok to face south or north, but there are conditions. Mostly big families like bureaucrats or landlords. Generally, it faces south for at least three yards, but most people dare not face south, that is, it is 15 degrees southeast, because the imperial residence is due south and north. Besides, one is trespassing, and the other is not so lucky. The first two entrances are visitors and rooms. There are two or three courtyards facing north, and the landlords here use them more. There is a ridge in the north, and the water is turbid, so the door is red. There is hardly any place now, and there is not such a big place. Even if there is, it can't be built. Nobody cares about this in the new era.
