How to find the Wenchang position?

Wenchang refers to the star called "Wenquxing" that dominates the fate of literati. The orientation of the family door is different, the placement position of the Wenchang Tower is different, and the placement taboos of the Wenchang Tower are different. The direction of the mountain that the Wenchang Star turns around is different, and this direction is called the "Wenchang position".

Wenchang Dijing says, "The Qian hexagram is all water, neither short nor long. In the sky it is like Kui Zhao, and on the ground it is Wenchang. Regardless of whether it is a yin or yang house, encountering it will bring good luck." A Wenchang Tower placed in the Xun (wood) position has nine (water) floors, while a Wenchang Tower placed in the Gan (earth) position has seven (gold) floors. Wenchang position is good for studying and makes people quick-witted.
Feng Shui says that "the sky is above the Ox star (vitality), and on earth it represents success in imperial examinations." The method of the Eight House School to find the Wenchang position is to place the study and the desk in the right position. The Qian house is in You and Geng, the Kun house is in Gen and Chou, the Gen house is in Kun, and the Dui house is in the Qian position (for people with the four western destinies). The Kan house is located in the Xunchen position, the Li house is located in the Maojia position, the Zhen house is located in the Wubing position, and the Xun house is located in the Ziren position (for people of the East Four Fates).
Generally speaking: if the house faces north and south, Wenchang is located in the northeast; if the house faces south and north, Wenchang is located in the south; if the house faces east and west, Wenchang is located in the northwest; if the house faces west and east, Wenchang is located in the southwest; if the house faces southeast and northwest, Wenchang is located in the southwest; if the house faces northwest and southeast, Wenchang is located in the east; if the house faces northeast and southwest, Wenchang is located in the north; if the house faces southwest and northeast, Wenchang is located in the west.
