Compass structure

Compass is an instrument to determine orientation, and air navigation is essential. Travel is also necessary. The auspicious star on the ecliptic (the earth's orbit) (the star that is illuminated by the sun and can shine by itself) and the fierce star in the underworld, and the yang base should welcome the auspicious and avoid evil spirits. The material properties and natural phenomena in all directions on the ground should interact with the orientation of the cation base to avoid mutual interference. The direction of water flow and the direction of anode base should be opposite. In order to measure accurately, you must use a compass.

Structure and content of compass: 1. The small transparent round box in the middle is called "Tianchi" to protect the magnetic needle. 2. The red magnetic needle pointing to the south under the action of geomagnetism is called "compass" and is the main part of the compass. 3. The north-south red line (some compasses don't) is called meridian. 4. Circle layer, with territory inside, human plate in the middle and sky plate outside. Select the disk you want to use as needed. There is a separate compass. 5。 The dishes list gossip, heavenly stems, earthly branches, constellations, jiazi, code names and so on.

Compass Day, "Compass Diameter 2 should be 12 months. Six of the three feet should be in it. The 24th floor should be 24 solar terms. Use it to collect the meaning of heaven and earth, dial the degree of stars, and examine the mountains and rivers (reading). Tianchi is in the middle. The twenty-four drums are different, with one meaning, two meanings and several meanings. " Luo Jing added: "Eight Diagrams began in Fuxi and flourished in the Zhou Dynasty." "Great pole gives birth to two instruments, two instruments give birth to four elephants, and four elephants give birth to gossip."

Two instruments refer to yin and yang, bright white represents yang, and dark represents yin. Black dots on a white background and white dots on a black background represent Yin in Yang and Yang in Yin respectively. For example, there are 12 hours day and night, and there are more than 12 hours a day from vernal equinox to autumnal equinox, which accounts for the night time, and there are yin in the yang. From the autumnal equinox to the vernal equinox, the night is more than 12 hours, accounting for the daytime, and it is sheltered in the shade. This is the sun, and the night is cloudy. Ming belongs to Yang, and dark belongs to Yin. Facing the sun belongs to yang, facing the sun belongs to yin.

Heavenly dryness is yin and yang, and A, C, E, G and nonyl belong to yang, while B, D, G, Xin and Gui belong to yin.

The yin and yang of the earthly branches belong to yang, and the ugly, ugly, old, young and young belong to yin.

These two instruments also guide the North Pole and the North Pole. Arrange with 12, and draw a straight line from "Zi" (North Pole) to "Wu" (South Pole), which is called meridian. The north uses "Zi" to indicate the distance from Dayang, and the south uses "Wu" to indicate the distance from Dayang. The compass is divided into two halves according to the length of sunshine, and four elephants are printed in the four directions of southeast and northwest.

The four elephants consist of 28 huts, each with seven constellations. Dongfang Jiao, Kang, Di, Fang, Xin, Wei and Ji are called Qinglong. Nanjing, Ghost, Willow, Star, Zhang, Wing; Seven stars, called South Bird Suzaku. Xikui, Lou, stomach and Chang. Bi, Gou and Shen are called white tigers. North War, cattle, female, tiger, danger, room, wall turtle snake, named Xuanwu. The four elephants are also called the four beasts.

Four horns are added to the horns of the four elephants, which becomes the divination position of all directions. The compass said, "Look up and see the image in the sky, bow your head and see the ground and descend to the law. Watch birds and beasts, stop at the right place. Take the body, take the distance, realize the virtues of the gods, and love everything. " Take Wang Wen's Gossip the Day After Tomorrow as an example. The earthquake belongs to the oriental thunder wood. It belongs to southern fire, western gold, northern water, southeast wood, southwest soil, northeast soil and northwest gold.

With the constant discovery of the universe, designers of compasses have different understandings, and the arrangement position of the eight codes has also changed. For example, Wang Wen's gossip (called the acquired gossip) represents the paradise in the northwest and the land in the southwest. Fuxi Bagua (called innate gossip) represents the sky in the north and the land in the south. They have different directions and represent the same content. If the stem represents the sky, it is male and belongs to Yang; Kun stands for earth, women and yin. The content beyond gossip is determined around the orientation of gossip. Therefore, the change of eight diagrams code arrangement and code type does not affect the use effect of compass. These are limited to the understanding of the historical conditions at that time. If the compass prevails in the future, there will be a new unified understanding.

Nine planets, namely Wolf, Giant Gate, Lian Zhen, Lucun, Pojun, Wu Qu, Wen Qu, Zuo Fu and Youbi.

Zodiac, that is, longevity, bathing, crown belt, temporary official, emperor, decline, illness, death, tomb, extinction, pregnancy and raising.

With Tianchi as the center, it is divided into 24 equal parts. Put the eight words "A, B, C, D, G, Xin, Ren and Gui" in the sky, and the six words "Zhi Zhi", "Ugly", "Yin", "Mao", "Chen", "Shen", "You" and "Female" in the gossip. Write the eight diagrams inside and outside the 24-direction circle according to the specified position, that is, the four seasons of spring, summer, autumn and winter, the five elements of golden water, fire, wood, water and soil, and the five colors of blue, red, white, black and yellow (or five elements), such as the 24 solar terms 12 Gongjiuxing and the auxiliary stars of the nine planets. Take the East as an example. The four elephants are Qinglong, Bagua Earthquake, Four Seasons Spring, Five Elements Wood, Five Colors Green, Twenty-four Solar Equinox, Earthly Branches Mao, Nine Planets Lian Zhen, and Auxiliary Star Tianheng.

24-direction is widely used, and every hexagram should be used. Divide 360 degrees into 24 equal parts, each equal part is 15 degrees. It is difficult to accurately determine the location of Yangji or her residence, which planet it should be on, what material phenomenon attribute it should be, and the direction of water flow and the ins and outs of the mountain shape of 15 degrees. The accuracy of 24-direction directly affects the use effect of compass.

"Jiazi" consists of 60 groups of heavenly stems and earthly branches, which are used to represent the year, month and day. The first group is "Jiazi", so with the title of "Jiazi" written in the grid related to the Eight Diagrams and Twenty-eight Nights, 64 hexagrams with the content of "Jiazi" and 24 inward hexagrams were calculated respectively. Each hexagram is divided into six hexagrams. Write a simple note on both sides of the coin. Mr. Feng Shui used this to make irresponsible remarks.
