What are the three essentials of Yangzhai and what are the taboos?

"Three Essentials of Yangzhai" was written by Zhao Jiufeng, a great Kanyu master in the Qing Dynasty. The so-called three essentials of a Yangzhai are the three important elements of a Yangzhai: 1. The door is the key to a Yangzhai, and is the way for a family to come in and out day and night, just like a person's mouth and throat, and there must be no mistakes. Avoid being low or dark, as this may lead to labor disaster. Avoid shooting from the neighbor's roof ridge, corner, eaves, or road. It will harm your wife and children. If you shoot directly at the center line of the door, your life will be injured. The door should be spacious and bright, surrounded by roads or streams, which means that both men and women will be prosperous, and men will be righteous and women will be virtuous. There is no specific position of the door, but the position of the nine stars is determined by the door. This is the door-turning star shift. 2. The Lord is a place for living and sleeping. The Lord and the Gate are in harmony with each other and cannot conflict with each other. The star placed in the Lord position must be in harmony with the Palace and cannot be in conflict with each other. When they are in harmony, they are auspicious; when they are opposite, they are inauspicious. 3. Stove. Food is the most important thing for people. Therefore, the stove is the place where people eat and drink. It is closely related. Firstly, it must be related to the door, and secondly, it must be related to the Lord. Thirdly, the star placed in the kitchen position must be related to the palace, which is auspicious. On the contrary, it is bad luck. When looking at a house, first look at the main door, then the main room, and then the kitchen. As long as the three are in harmony with each other, it is a auspicious house, and the owner will have both wealth and longevity. If they are in conflict with each other, it is a dangerous house.
