There is a saying in Feng Shui that the south is high and the north is low?

What is the saying that geomantic omen is high in the south and low in the north? However, China or the Northern Hemisphere is not conducive to houses or houses. Why do you say that? We all have the southern sun in winter, which is high in the south and low in the north. It is bound to be cold and attacked by the north wind. So feng shui is impossible to break up. Whether you are a house or a prostitute, the south is the best, and the north is the best and the most auspicious, that is, living in a cemetery is the safest.
