What does Wenchang mean? How to judge Wenchang specifically?

A term in geomantic omen comes from Zhouyi. Wenchang position is the position where wenchang star flies into the house. Every family has this tendency. As long as the study or desk is located in Wenchang, it will be beneficial to reading, writing and planning. According to geomantic theory, Wenchang position is determined by the orientation of the house, such as the door facing west and the house sitting east facing west, which is the Earthquake Palace: 1. Earthquake houses sit in the east, west and northwest. 2. The earthquake house is located in the southeast facing the northwest and the south facing the southeast. 4. Kun Zhai sits southwest facing northwest and west facing southwest. 6. The dry house sits in the southwest, facing northeast and east. 7. Kanzhai sits facing south and northeast. 8. The root house sits northeast facing southwest and north facing southwest. Due to congenital structural problems, Wenchang can't be used as a study, so he has to settle for the second best. Put the Wenchang Tower purified by imperial salt in Wenchang's position, and then place a stone tablet amulet made of red bamboo stone and shadow stone in the east of the study. Or girls usually wear orange stones and boys wear shadow stones. If Wenchang happens to be the kitchen and bathroom in the innate pattern, it must be placed in this position, and the red bamboo stone, orange stone, sea of clouds stone, indigo crystal and shadow stone will be made into a stone tablet amulet to resolve the impact of Wenchang. And girls generally need to wear blue velvet crystals, and boys generally need to wear shadow stones.
