Is Yang Gong's "Seventy-two Dragons" a fake Feng Shui?
One: Seventy-two dragons, every dragon five degree, but in the Tang Dynasty, such a fine compass could not be made anyway.
Second, the compass was discovered after the Song Dynasty and was widely used in navigation. Hundreds of years have passed since Yang Gong's time.
Three: Seventy-two dragons in the actual operation of geomantic omen, such as Pinggang, Shanlong, various situations of dragon operation, and the height, fat, thin, wide and flat of Shanlong. It is absolutely inaccurate to regard seventy-two dragons as dragons, even the mechanical operation cannot be accurate within five degrees. What's more, there was no modern craft compass in the Tang Dynasty more than 0/000 years ago.
This is incompatible with Yang's "dragon method" program, because once an error occurs, the dragon is another concept of five elements, and the quality is completely different. Therefore, after seeing a lot of mountain dragons, the earth division with a little experience in chasing dragons and driving mountains can veto 72 dragons with one vote. Moreover, the existing tools in the Tang Dynasty are difficult to be accurate to seventy-two dragons and five degrees. This was determined by the manufacturing process at that time. It is an objective condition that cannot be changed. As for any theory, it has its fulfillment and unverifiable, which is not the content of this paper. In fact, there are many puzzles in the textual research of Yang Gong's handwriting in Jiangxi.
Moreover, there is absolutely no need to use the seventy-two demon-yin-yang dragon method in countless handwritten works. As for the seventy-two dragons, it was produced after the Song Dynasty when Neo-Confucianism flourished. Many inventions and achievements were made in the name of predecessors. Why did Li Chengong's style in Song Dynasty appear after Song Dynasty? You can only know earthworms when you are a prophet and a tiger is on the mountain. When the mirror is opened in cloudy days, the golden moon meets the water. The tiger crossing the mountain is seventy-two dragons, and the earthworm is sixty jiazi dragons. This is the earliest record of the 72 dragons.
2. Yang Gong's orientation tools.
So Yang Gong doesn't have the tools to be accurate to a few degrees, so how can he position himself? That is, visually, with the bamboo stick in his hand, he followed the pulse of the mountain dragon with the "inverted stick method", leaning forward while leaning back, flashing left and right, and so on. , so that he can determine his position. Some people will ask, can you locate vertically without a compass? Yang Gong gave the answer and did it. This is the kung fu of the upper legalists. The Guan ancestral hall established by Mantongba in Yaokoufang is known as the "bench-style" ancestral hall in the world. Because of the story of bench orientation, it has been passed down to this day. In fact, there are many such stories in Yang Gong's long-term geomantic activities. More often, the bamboo stick in his hand became his directional tool.
If Yang Gong uses a small rough wooden compass, let's infer:
One: Due to the limited level of history and technology, plus the Twenty-four Mountains, the Star Star, the trunk branch and the first floor of Pantian in Shuang Shan, it is impossible to have as many complicated levels as the modern compass. You can only push so much. There is a small pool in the log plate, which is filled with water, so it was called "Tianchi" in ancient times. An artificially magnetized compass is put into the water, and its direction can be identified by its buoyancy in the water.
Two: There is no water injection in the middle of Tianchi Lake, but a magnetic needle erected in supporting shaft. This is much more convenient than putting it in water. You don't have to go to any mountain, you need to prepare the water source for holding the needle, which is easy to sprinkle the needle.
Note: The technical level of setting the magnetic needle in the support shaft has aroused great discussion in the scientific community. The appearance of this kind of compass is called dry compass and water compass is called water compass. Its strong archaeological persuasiveness only appeared in ancient tombs and navigation applications in the Song Dynasty. Therefore, the technical level is the first decisive factor to determine the development of compass. Whether it is a water compass or a dry compass, it was only used in the navigation technology of the Song Dynasty. At present, the scientific and archaeological circles can strongly prove that it only appeared in the Song Dynasty. Whether there were any objects in the Tang Dynasty or whether Yang Gong used a compass is still inconclusive.
But I don't know what tools the ancestors used, so why talk about the methods they used? So it also creates a lot of imagination and space for Feng Shui. It seems that any sect or theory can play the Yang Gong card or borrow Yang Gong's name.
3. The doubts about the compass are recorded in the relevant scriptures.
Although the compass was used for navigation in the Song Dynasty, Feng Shui artists also used it to orient tools. So it is said that the compass was invented by the Kanyu family.
In the Tang Dynasty's Xue Xin Fu, the servant recorded: "Establish a prescription and correct it with a meridian needle", so what is this meridian needle? Is it a compass or a magnetic needle? So it is necessary to find out. This may be an earlier compass, twenty-four dharmas, branches of heaven and earth, and twenty-four mountains. If it is a compass, the history of the compass will be pushed to the Tang Dynasty. In fact, there is no strong proof yet.
In the Northern Song Dynasty, Shen Kuo's "Meng Qian Bi Tan" volume 24 said: "The Fang family can be guided by a magnet grinding needle." Then the meridian needle mentioned by servant Yingtian refers to the artificial magnetization of the compass. Not a compass.
4. Early understanding of compass form and archaeology.
The invention of compass has no exact time and inventor. Ceng Gongliang's General Theory of Martial Arts in the Northern Song Dynasty mentioned that "compass fish" was used to help identify the direction when marching. As for the "compass fish", it is a fish-like steel plate, five minutes wide and two inches long, with a sunken abdomen and a shape like a boat. After magnetization, it floats on the water to distinguish the north from the south.
Shen Kuo in the Northern Song Dynasty recorded in Meng Qian Bi Tan that besides the compass, the direction of the compass should also be determined by the azimuth plate. When you first use a compass, you may not have a fixed azimuth dial. With the need of azimuth measurement, a compass with integrated magnetic needle and azimuth disk appeared.
This was determined by the manufacturing process at that time. It is an objective condition that cannot be changed. As for any theory, it has its fulfillment and unverifiable, which is not the content of this paper. In fact, there are many puzzles in the textual research of Yang Gong's Jiangxi handwriting.
Moreover, there is absolutely no need to use the seventy-two demon-yin-yang dragon method in countless handwritten works. As for the seventy-two dragons, it was produced after the Song Dynasty when Neo-Confucianism flourished. Many inventions and achievements were made in the name of predecessors. Why did Li Chengong's style in Song Dynasty appear after Song Dynasty? You can only know earthworms when you are a prophet and a tiger is on the mountain. When the mirror is opened in cloudy days, the golden moon meets the water. The tiger crossing the mountain is seventy-two dragons, and the earthworm is sixty jiazi dragons. This is the earliest record of the 72 dragons.
