Detailed explanation of the development history of Feng Shui compass!
Introduction: I believe that few people know some knowledge about the compass, and few people know that the compass was developed based on the compass, one of the four great inventions of my country! So what is the development history of the compass? Let’s follow the editor to learn more about it below! Want to know more articles and content related to the compass? Welcome to the compass special topic that Mr. Shui Mo has carefully prepared for you to learn more knowledge. Come and have a look! Feng Shui prosperity is a good thing. However, there are so many schools of Qi and Feng Shui that it is difficult to reach a consensus. Many people claim to have received the true teachings of Yang Gong. For example, the Sanhe School, Luantou School, and Xuankong School all claim to be the authentic descendants of Yang Gong.

1. The Compass Chariot - Chi You

The compass is a great invention of the ancient Chinese. The ancient Chinese discovered magnets very early. Legend has it that when Huangdi fought Chiyou, he used the help of the compass chariot. It is said that this was the shape of the compass chariot at that time. The people in the car can point out directions.
2. Sinan - Warring States Period The Sinan of the Warring States Period is the ancestor of the compass. This is clearly recorded in text and pictures.
In addition to the symbols of the Later Heaven Bagua, the Si Nan is also engraved with the Heavenly Stems and Earthly Branches and the Twenty-Eight Mansions. The eight stems, four trigrams and twelve branches constituted the twenty-four mountains in the compass later. Sinan is the prototype of the compass. It has a square shape and no 360-degree scale around it. Since the magnetic needle is a spoon, it is definitely not very convenient to carry.
Wang Chong of the Eastern Han Dynasty said in his "Lun Heng. Shi Ying Pian": "The handle of the Si Nan instrument, when thrown on the ground, its base points to the south." The "ground" here refers to the chassis in the picture above. There are many records about Sinan in ancient books from the Warring States Period, Qin and Han Dynasties, Six Dynasties to Sui and Tang Dynasties.

3. Compass Fish – Northern Song Dynasty

Later, ordinary people often cut thin iron sheets into fish shapes, with the belly of the fish slightly concave, like a small boat. After being magnetized, the fish fillets will float on the water and point to the north and south. Cui Bao of the Eastern Jin Dynasty mentioned this "compass fish" in his "Notes on Ancient and Modern Times". At that time people treated it as a game.
During the Northern Song Dynasty, Zeng Gongliang recorded the method of making and using the compass fish in "Wu Jing Zong Yao": "Use a thin iron sheet to cut a length of two inches and a width of five fen, with the head and tail sharp like a fish shape, and burn it in a charcoal fire. When it turns red, use an iron seal to seal the fish head out of the fire, and place the tail directly in the middle of the water. Dip it in a basin of water until the tail is submerged for several minutes, and then store it in a sealed container. When using it, place a bowl of water in a windless place and place it flat. The fish is on the water surface and floats, with its head always facing noon."

4. Compass Turtle - Before the Ming Dynasty

There is another game that existed before the Ming Dynasty. The iron sheet is magnetized and made into a turtle shape with a fulcrum in the turtle's belly.

5. The compass in Mengxi Bitan - Northern Song Dynasty

Shen Kuo, a scientist in the Northern Song Dynasty, recorded four methods of installing a compass in his "Mengxi Bitan".
First, the water float method - put a few rushes on the magnetic needle and float it on the water to indicate the direction.
Second, the bowl lip rotation method - place the magnetic needle on the edge of the bowl, the magnetic needle can rotate to indicate the direction.
Third, the fingernail rotation method - place the magnetic needle on the fingernail. Since the nail surface is smooth, the magnetic needle can rotate freely and indicate the direction.
Fourth, the hanging thread method - apply some wax on the middle of the magnetic needle, stick a piece of silk, hang it in a windless place, and it can indicate the direction.
Shen Kuo also compared the four methods. He pointed out that the biggest disadvantage of the water float method is that the water surface is prone to shaking, which affects the measurement results. The bowl lip screwing method and the fingernail screwing method are very flexible to rotate due to the small friction, but they are easy to fall off. Shen Kuo preferred the method of hanging with silk, which he believed was a more ideal and feasible method.
The four methods pointed out by Shen Kuo have summarized the two major systems of compass devices to date - water needle and land needle.

6. Compass – Southern Song Dynasty

Pingzhou Ke Tan, which was written slightly later than Mengxi Bitan, records: "The sailor knows geography. He observes the stars at night, the sun during the day, and the compass when it is cloudy." This is the earliest record of the use of the compass in the world's navigation history. The article points out that the compass was only used when the sun, moon and stars were not visible. This shows that the compass was just beginning to be used and people were not yet proficient in its use. Twenty years later, Xu Jing's "Xuanhe Fengshi Gaoli Tujing" also had a similar record: "Just look at the stars and move forward. If they are dark, use the floating compass needle to measure north and south."
During the Southern Song Dynasty, Zeng Sanyi recorded in "Yinhualu": ​​"The compass may have a north-south needle, or a sewing needle between the north-south, Bing and Ren." The "compass" mentioned in the literature is the compass, or the compass plate. The knowledge of magnetic declination has been applied to compasses in the literature. This kind of compass not only has a meridian needle (a magnetic needle that determines the direction of the north and south poles of the geomagnetic field), but also a meridian and meridian needle (the directions of the geographical north and south poles determined by the sun's shadow). The angle between these two directions is the magnetic declination.
By the Yuan Dynasty, the compass had become the most important instrument for navigation at sea. We use a compass to navigate regardless of day or night, whether it is sunny or cloudy.

7. Hanluo Pan - the real Feng Shui compass Southern Song Dynasty

The dry compass first appeared in the Southern Song Dynasty and was used for Feng Shui. This is the earliest use of a compass discovered in archaeological history.
In May 1985, a large number of pottery figurines were unearthed from the tomb of Zhu Jinan in Moyuanli Village, Wenquan Township, Linchuan County, Jiangxi Province in the fourth year of Qingyuan in the Southern Song Dynasty (1198). Among them was a figurine titled "Zhang Xianren", which was 22.2 cm tall and held a large compass in his hand, resembling the image of an ancient Feng Shui master. The magnetic needle installation method of this compass model is different from that of the water floating needle in the Song Dynasty. There is an obvious round hole in the center of its diamond-shaped needle, which vividly shows the structure of using an axis support. It eloquently proves that as early as the 12th century, my country had used the dry compass to determine its direction.
So in fact, in the Tang Dynasty, Yang Gong did not necessarily use a compass when he looked at Feng Shui. Even if a compass is used, it may not necessarily contain the contents of the current compasses which have as many as fifty-two layers. This is beyond doubt!
It was during the Song Dynasty that the twenty-four mountains on the compass were changed from one plate for land to three plates for heaven, earth and man. Everyone who studies Feng Shui knows this. The compasses of the Song Dynasty were already very accurate, but later compasses became more and more complex. Seventy-two dragons that penetrate the mountains, one hundred and twenty points of gold, three hundred and sixty degrees, three hundred and eighty-four hexagrams and so on were added. Feng Shui became more and more complicated and deviated more and more from the mainstream of Yang Gong, and the pseudo-Feng Shui technique was passed down from generation to generation.
No matter whether it is Sanhe, Bazhai, Flying Stars or Da Gua, historical facts cannot be ignored when interpreting Yang Gong's classics.
