How to use the Luo mirror

The compass, also known as compass, compass mirror, sutra pan, compass pan, etc. in ancient times, is an indispensable tool for ancient Chinese astrologers to engage in compass activities.

The compass is an important tool for Feng Shui operations, and its basic function is orientation. When we understand the knowledge of Feng Shui and Qi regulation, we must first learn the basic method of compass orientation.

The scientific name of the compass is Luo Jing. It was created in the time of Emperor Xuanyuan. Later, through the sages of the past dynasties, according to the principles of the Book of Changes and Heluo, the sun, the moon, the five stars, the seven political principles and the principles of the movement of the astronomical stars were used to observe the mountains and rivers on the earth. Rivers and plains are made by modifying and improving the undulating shape of the waves. They are used to determine the direction and survey the terrain. Most of them are called "Compass" or "Luogeng" by Kanyu geographers and sailors, and rarely called "Compass".

Speaking of how to use the compass, if it were discussed in detail, I believe it would take a lot of space. Because it includes so many things, this article will only talk about simple usage methods.

There are many types of compasses. The commonly used compasses are three-yuan compass, three-in-one compass, three-yuan three-in-one dual-purpose compass, Yi compass, Xuankong compass and the unique compass of each school user. But no matter which sect's compass it is, there must be a layer in the middle with the directions of the twenty-four mountains. Starting from the north, they are Renzigui, Chougenyin, Jiamaoyi, Chenxunsi, Bingwuding, Wei Kunshen, Gengyouxin, Xuqianhai and so on. ***Twenty-four directions.

If you have a compass, you can find that the degrees relative to the compass and the pointer are as follows:

Clear the direction of the Twenty-Four Mountains Finally, now let’s look at the shape of the compass.

From the shape of the compass, you can see that in the center of the compass is a circular Tianchi (that is, a compass for orientation). On the outside is a movable turntable with gold characters on a black background and a copper surface, which is called the inner disk or disc. The plate is filled with words in circles. It is customary to call a circle a layer. There is one layer with twenty-four directions, and the outermost is a square plate, called the outer plate or square plate. The disc body is made of rosewood, which is the most durable, but is heavier than ordinary wooden discs.

The outer plate has four small holes, and two fish wires or glue threads are passed through the small holes in the middle of the four sides in a cross shape. They are used to determine the sitting direction.

The main use of the compass is the central magnetic needle. The inner disk outside Tianchi is made of steel. The background color of Tianchi is usually white, with a red straight line drawn at the bottom and two red dots on one end of the red line. Left and right, the red line is positioned in north and south. The side with the red dot is Zifang (due north), and the other end is Wufang (due south). There is a very sensitive magnetic needle on it, and there is a small hole at one end of the magnetic needle.

When using the compass, hold the outer disk with both hands on the left and right, with your feet slightly apart. Place the compass between the chest and abdomen. Keep the compass level. Do not raise the left side higher than the right lower, or the front higher than the back. Low. Then use your back as your seat, face your face as your orientation, and start standing.

At this time, the cross lines on the compass should coincide with the four correct positions of the front, back, left, and right of the house. If the cross lines are not in the correct direction, then the measured There will be deviation in the sitting direction.

After fixing the position of the cross fish wire, use the thumbs of both hands to move the inner disk. When the inner disk rotates, the Tianchi will rotate accordingly. Keep rotating the inner disk until the magnetic needle stops and overlaps with the red line in Tianchi.

One thing is very important, that is, the end of the magnetic needle with the small hole must coincide with the two small red dots on the red line, and the positions cannot be offset from each other. At this time, it shows that the fish silk line in the sitting direction (the horizontal one) intersects with each layer of the inner disk. The various data and information we are looking for are displayed on the area traversed and covered by this fish line.

However, there are more than ten or twenty levels on the compass. Which level should you sit on? It's the level of Mount Twenty-Four. It is near Tianchi. We use the "mountain" on the direction of the fishing line to indicate direction, and the "mountain" on the side of the fishing line to sit on, we use it to indicate sitting.

For example, facing the mountain is Zi, and sitting on the mountain is Wu, so we call it sitting at Wu and Xiangzi. Once you know where you are sitting in your house and put the compass at the center of the house, you can find the direction (or palace position) of the house from the direction you are sitting.
