What is the difference between the orientation of the Eight Diagrams, the orientation of the Seven Stars Modern Geomantic omen, and the orientation of the Eight Houses School Geomantic omen and the orientation of modern geography (map)?
Zhengua (due east), Haigua (southeast), Ligua (due south), Kungua (southwest), Dugua (due west), Gangua (northwest), Kangua (due north) and Gengua (northeast).
the directions of the second and seventh stars correspond to the modern directions:
Yibai (due north), Erbai (southwest), Sanbi (due east), Silv (southeast), wuhuang (Zhonggong), Liubai (northwest),
Qichi (due west), Babai (northeast) and nine purple (northeast). According to the song "Kuntianyan is doomed to disaster in May and June", we know that the modern orientation is as follows: Kunming Palace in the southwest is a crouching position, Zhengxidui Palace is a heavenly doctor, Northwest Gangong Palace is a life-prolonging, Zhengbeikan Palace is desperate, Northeast Gengong Palace is angry, Zhengdongzhen Palace is a disaster, Southeast Xungong Palace is a five-ghost, and Zhengnanli Palace is a six-evil. And so on. If the gate faces the northeast, it will be in the three mountains of "Ugliness, Genu and Yin" of the twenty-four mountains in actual geography. It is worth noting that it is not suitable to open the door for the "Ghost Gate Line" within 15 degrees of Gengu.
therefore, you should choose ugly and yin to open the northeast gate.
