It is best to erect a rectangular room, that is, take the intersection of diagonal lines as the center, put a compass at the center point to aim at the north and south, and then extend outward according to the eight directions on the compass, and the Jiugong will come out. If you don't have a compass, use a compass, or make one yourself: just rub the magnet with a sewing needle, then put it on a small piece of paper and put it in the center of a glass of water.
Irregular houses are the hardest to stand upright, and I don't know. Look at the pictures, I can't help you here. I have read How to Stand Up Straight in Feng Shui Tian Di written by Song Shaoguang.
Secondly, I came up with a simple and easy-to-understand statement. The first arrangement is used to "judge the quality" of the built houses; The second type is used to drain geomantic omen, but in fact, both the first and second types are used to drain geomantic omen, so we should drain two types and then choose the appropriate one to use. For example, if there is luck in nature, we will use it in nature; if not, we will choose the day after tomorrow. Feng shui is not static.
There are many ways to start divination, such as divination with characters, divination with sounds, divination with objects and so on. The following is the "divination method":
When you shake the hexagrams, first put three copper coins (the best is the dry dragon coins) flat on the palm of your hand and put your hands together for about one minute. Your mind will only think about what you want to predict, shake the copper coin six times and write down the symbol each time.
The usage of copper coins is that the side with words is a cross and the side without words is the back. If one of the three copper coins has a back, it is recorded as ",",which is a single yang; The two backs are marked as ","and ",which means disassembly and yin; Three times, draw a circle of "O", which is to emphasize harmony and yang; Three characters, recorded as "X", are horizontal and yin.
A circle or a point, an "X" or two points. Yang movement has an "O" and Yin movement has an "X". "O" and "X" are the themes in hexagrams. If you move, you will change, Yang will change to Yin, and Yin will change to Yang. Six of the six hexagrams move completely, and then all change; Six sticks don't move, don't change. One is shaoyang and the other is shaoyin; An "O" is Lao Yang, a thing of the past; An "X" is the old yin, which is the main one in the future. "O" means dynamic and "X" means variable.
Now take shaking a six-pointed star as an example (write down each six-pointed star from bottom to top):
On x, x is a cross and a yin-
Exotic hexagrams and five hexagrams are the same thing: one is yang and the other is ze.
O four circles, one dot and one yang.
,, and three points are divided into yin-
Neibu, divination and divination are divided into yin-earthquake means thunder.
O one point on the first lap, one yang on the first lap.
The hexagrams are arranged from bottom to top, and the names are arranged from top to bottom. The external divination of this kind of divination is exchange, and the internal divination is vibration, which is the divination of Sui Dynasty.
