What kind of evaluation system is Feng Shui?

With the passage of time, Feng Shui has become a geographical and topographic taxonomy associated with the activities of Mr. Feng Shui (also known as Yin Yang Jia). It is related to environmental science, but it is explained by superstition and ghosts. Basically, it is an evaluation system for choosing auspicious days and finding auspicious places for buildings and cemeteries (yangzhai and yinzhai). The mature Yin-Yang theory and Five Elements theory in the Western Zhou Dynasty directly penetrated into Feng Shui, which included geographical and topographic taxonomy and environmental knowledge, the oldest ancestor worship concept and afterlife theory. Until today, it still plays a role in some people's housing choices.
