How to hold and use a compass

How to hold and use a compass

Before using a compass or compass, you need to pay special attention to the following points:

1. You must first Remove all ironware, electrical appliances (mobile phones, walkmans...) or objects that may interfere with the compass magnetic field.

2. Please note that there are no iron objects, mobile phones, telephone poles, electric boxes, electric towers, etc. that may interfere with the electromagnetic field near the measurement site.

3. The surface of the compass or compass (north) needle must be kept level, and the pointer must not be raised or lowered on one side. At the same time, attention should also be paid to whether the joint between the compass surface and the disk body is tight, and there must be no looseness or looseness. rupture.

4. Check whether the compass or compass (north) needle is normal. If it is bent, do not use it.

1. The correct way to hold the compass:

Picture A

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 and keep the compass horizontal. It should not be higher to the left or lower to the right, or higher in front or lower in the back.

Adjust the compass so that the crosshair line above the compass should be parallel to the door of the house (refer to Figure A).

Adjust the pointer direction:

Picture B Tianchi

Picture C Adjust Tianchi

After fixing the position of the cross fish wire, you need to Start adjusting the direction of the pointer in Tianchi.

Use the thumbs of both hands to move the inner disk. When the inner disk rotates, Tianchi will rotate accordingly. Keep rotating the inner disk until the magnetic needle stops (Figure C) and overlaps with the red line in Tianchi.

Method for judging the seating orientation

Figure H, top view

Figure I, side view

In the explanation of the seating orientation of the house, it has been emphasized The way to determine the seating direction is to stand in the house and face the direction of the door. In this way, the back is the seat and the face is the direction.

Because the magnetic needles of compasses and compass (north) needles are easily affected by electrical appliances and ironware in the home and cause declination, when measuring the azimuth direction, it is recommended to measure it outside the house in an undisturbed place.

When measuring, it is recommended that you face the door of the house and look into the house as shown by the arrow, so as to adjust the compass so that it is parallel to the house, and then start to rotate the inner disk to calibrate the magnetic needle; at this time, it is Take the face as the seat and the back as the orientation. That is, if the back is south and the face is north, then the seat is north facing south. This is slightly different from the method introduced previously, so special attention is required.

Please refer to Figure I for how to hold and use a compass or compass. Facing the door of the house, keep the compass or compass parallel to the house, adjust the pointer to north (south), and obtain the direction of the house. and angle.

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 affairs 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".

There are many types of compasses, the commonly used ones 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, etc., ***24 directions [the core of the compass is actually the compass, used to identify directions, combine the Eight Diagrams with the Heavenly Stems and Earthly Branches] ***24 characters are engraved on The periphery of the compass is the compass. These 24 characters are 12 heavenly stems + 8 earthly branches (except Wu and Ji) + 4 hexagrams (Qian, Kun, Gen, Xun), also known as the twenty-four mountain directions].

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

The origin of the twenty-four mountains

The compass initially had only two poles: north and south. Later, east and west were added to form the four major directions (east, west, south, and north). Later, the compass added eight directions to east, west, south, and north, making it twelve directions. Formed the earliest compass.

Picture F: The hexagram position and the mountain correspond to the diagram

The twelve directions are recorded with the twelve earthly branches, namely Zi, Chou, Yin, Mao, Chen, Si and Wu. , Wei, Shen, You, Xu, Hai; the twelve earthly branches represent the twelve directions of the earth, which are called twelve mountains in Feng Shui.

Later on, with the development of the compass, the original twelve directions were further divided into twenty-four directions. Among the twelve newly added directions, eight of them were represented by the Ten Heavenly Stems: A, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, Gui, and the other four missing ones are represented by Gen (Northeast), Xun (Southeast), Kun (Southwest), and Qian (Northwest) in the hexagram , becoming the twenty-four mountains on the compass.

The twenty-four mountains are represented by eight hexagrams, namely Kan, Gen, Zhen, Xun, Li, Kun, Dui and Qian. (Refer to Figure F)

After knowing the direction of the Twenty-Four Mountains, now we need to look at the shape of the compass.

You can see from the shape of the compass 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 magnetic needle in the center. 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.

Before operating the compass, you should silently recite "Lowering the Compass" three times. The secret says: "The sky spins and the earth spins and the nine stars spin, the yin and yang are in harmony and reverse, showing the gods. The five elements are in their respective positions, seeking good luck and avoiding bad luck, so as to avoid misfortunes and bring down the whole."

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 horizontal. 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 the son, and sitting on the mountain is the noon. We call it sitting on the mountain and facing the son.

If you know where you sit 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 sit.

2. Application of the "three disks and three needles" of the compass

1. Ground - used for vertical direction - place a "compass or compass" on the Tai Chi point to measure all directions. The Tai Chi point of the Yang residence is in the middle of the house; the Tai Chi point of the Yin residence is in the center of the tomb.

2. Human tray - used to eliminate sand - look at mountain peaks, buildings, trees, walls, piles, towers, chimneys, etc.

3. Sky plate - used to receive water - to see the coming and going of water or the direction of the road. Such as water, rivers, ponds, wells, toilets (turbid water), fish farming (moving water), doors and windows (moving water), roads or flat ground (virtual or false water), etc.

3. The method of receiving water with Bagua attributes:

1. Qian Gen Kun Xun belongs to wood.

2. Yixindinggui belongs to earth.

3. Ziwu, Maoyou, Jia, Geng and Bingren belong to fire.

4. Chen Xu Chou is not a metal.

5. Yinshensihai belongs to water.

4. Attributes of Bagua:

1. Wood overcomes earth and is wealth.

2. Water-grown wood is the most valuable.

3. Seeing wood is prosperous.

4. Wood producing fire is catharsis.

5. Metal defeats wood to kill.

How to use:

For example, Kunshan Gen Xiang Jian Weichou, Sitting Ding Wei shares gold with Ding Chou, ascends the four lines of the hexagram, and turns it into the hexagram "Leifeng Heng Gua" "The eight games of the giant gate are drawn and the symbols are changed." Just sit on the mountain and raise the four lines of the hexagram to become the "Lei Feng Heng hexagram" to check the word. Lei Fengheng, Zhen Yamu, Xun Ermu. This hexagram predicts: Dongchu will be in position, two trees will form a forest, and he will gain fame and wealth. The land is prosperous, the eldest son and the eldest daughter are well-matched and obedient, the sons are noble, the virtuous are the grandchildren, the brothers and fathers share the respect, both wealth and honor are achieved, and the academic achievements are continuous. Note: This hexagram can be found in (The Encyclopedia of Usage of the Sanhe Sanyuan Compass, page 414 of "The Eight Bureaus of Jumen Extracting Yao and Changing Images".

5. How to use the compass

To learn Feng Shui, you must know the direction of the building. Now I will teach you how to use the compass to measure the eight directions.

The small magnetic needle in the compass points to north and south, and on the bottom of the magnetic needle, there is a straight line and the words E, S, W, N, etc. printed on it.

How to use:

1. Stand at the center point of the house and take out the compass.

2. Then make the magnetic needle in the compass overlap the straight line at the bottom.

3. Generally speaking, high-quality compasses have two colors, and the color of the magnetic needle is the same as the color of the bottom line, which is north.

For example, the color of the magnetic needle is half red and half black, and the straight line at the bottom is red. If you stack the magnetic needle on the straight line, because the bottom is all red, the red part of the magnetic needle points to the north, and the straight line If there is an S at the beginning, it means the south, if there is an N, it means the north, if there is a W at the end, it means the west, and if there is an E, it means the east.

After the magnetic needle is stacked on a straight line, the direction can also be calculated from the degree.
