Chinese classical philosophy believes that the "Five Elements" are the five basic elements in the universe. Representation is broad. 1. Representative directions: wood in the east; fire in the south; gold in the west; water in the north; earth in the center. 2. Represents seasons (seasons): spring wood; summer fire; autumn gold; winter water; earth at the end of each season. 3. Representative colors: green wood; red fire; platinum; black water; loess. 4. Represents the five internal organs: Liver Wood; Heart Fire; Lung Metal; Kidney Water; Spleen Earth. 5. Represents emotions: angry wood; happy fire; sad metal; frightened water; longing for earth. 6. Representative Heavenly Stems: Jia Yi Wood; Bing Ding Fire; Geng Xin Metal; Ren Gui Water; Wu Ji Earth. 7. Representative earthly branches: Yinmao wood; Siwu fire; Shenyou metal; Haizi water; Chenxu Chouwei earth. 8. Represents the Eight Diagrams: Zhenxun wood; Lihuo; Duiqianjin; Kanshui; Kungen soil. Through the contradiction and unity, balance and imbalance of the five elements' generation, restraint, control and transformation, everything in the world can be produced, and good, bad, misfortune and blessing can be produced. If you delve deeper into its principles, you can discover its endless mysteries! The specific five-element orientation map is as follows: Fire, Wood, Earth, Metal, Water The above five-element orientation map (which must be remembered) is Eastern Wood (please pay special attention that the orientation in the map is based on the orientation in the "Book of Changes", not modern The direction of drawing a map), gold in the west, water in the north, fire in the south, and earth in the center. This direction makes perfect sense. We also had mines in the Ming Dynasty. There was no geology at that time. How did we know where there were mines? Although some were discovered by local residents, most of them relied on the principles of the Bagua and the Five Elements to determine the center of the five elements. Western gold, in Tibet, the further to the west, the more gold is hidden. Oriental wood, the plant is prone to hair growth and is early exposed to the heat of the sun. The south is hot and the climate is hot. The north has the most water, ice and snow. At first glance, it seems that the orientation of the five elements is very chaotic. After careful observation, it cannot be said that there is no reason for it. How did the ancients discover this law? Take gold as an example: Metal generates water, in the "Thousand Character Essay" - this article is wonderful. It is written in a thousand different words, covering astronomy, geography, physics, politics, etc. When I entered it, it seemed that it didn't matter when I was young. It was actually a great work. There was a line in it, "Gold is born in Lishui." This Lishui is not Lishui County in Zhejiang Province. Lishui refers to a lot of water. Any place where gold is hidden must be in a rain belt area. When I first arrived in Taiwan, I saw the Gold and Copper Mining Bureau. I asked about the gold-producing areas in Jinshan and Ruifang. I said there must be a lot of rainfall there. Sure enough, it rains often in Keelung, Jinshan, and Ruifang. This is " "Gold produces beautiful water", and there is a lot of rain in places where gold is hidden. Metal beats wood. Of course, you need to use iron tools or saws to cut wood. This is not surprising. In ancient times, if there was a big tree at the door and the feng shui was not good and it was troublesome to cut it down, it would be better to let it die by itself. Just hit the center of the tree with a big iron nail and the tree would soon wither. This is the phenomenon of Jin overcoming wood. Another philosophical principle, for example, metal produces water. In ancient times, it was said: "Water is the son of gold." Water is the son of gold, so water produces wood, wood is the son of water, wood produces fire, fire is the son of wood, and fire produces earth. , Earth is the son of fire, earth produces gold, and gold is the son of earth. To overcome is to overcome each other across generations. There was a joke once upon a time, a grandfather beat his grandson, but his son saw it and slapped himself. The grandfather who beat his grandson asked his son why he slapped himself. His son said: "You can slap my son, why don't I?" Can I beat your son?" This is close to the five elements being in conflict, and this is also true. The so-called conflict between generations is bound to change every three years. This is a rule. In the midst of birth and restraint, kindness is born from harm, and harm begets kindness. In terms of military philosophy, after a war, it can promote the progress of human civilization, so sometimes I feel that war is not terrible, it is equivalent to getting a haircut. If the hair is long, it will look beautiful if it is shaved. There are many friends who talk about military philosophy, and it makes sense to use this law of generation and restraint of the five elements. The same is true for the laws of physics. At some point, things need to be cleaned up before newer things can be created. This is the law of the universe. The position of the five elements has a great bearing on our study of physics, so everyone must remember it.
