What is the origin and profound meaning of Luoshu and Hetu?

Luo Shu was called ghost book in ancient times. Legend has it that there is a turtle from Luoshui, and this image is on its shell. The structure is to wear nine shoes, three on the left, seven on the right, two on four shoulders, six on eight feet and five in the middle. The five white circles on five sides are all positive, and the four black spots on four corners are all negative. It was pointed out by predecessors that the number of Luo Shu originally came from the ninth house, just like hitting the stars with forty-five numbers. Nine palaces and eight winds combined with eight winds and eight gossip, and the central palace, namely the Luoshu Palace, is the core of the surrounding eight palaces. The ancients observed the celestial phenomena and thought that the position of Polaris (Taiyi) had always lived in the north, which could be used as the standard for locating the center. According to bucket handle, Jiugong is to find out the brightest stars in nine directions from celestial bodies as a sign, so that bucket handle can find the position and quantity of the nine planets, that is, the position and quantity of Luoshu. How can you go to the ninth house with the North Pole in the middle? It has been pointed out by predecessors that as the North Pole, it is used for Beidou, and the bucket is the emperor's car. It is said that Beidou is the car of the Arctic Emperor Star, and it is the image of the Arctic Emperor Star riding around the North Pole. If we can infer the meteorological changes at four o'clock and eight days according to the orientation of bucket handle's rotating finger, that is, nine represents different time series. Luo Shu is a star located in the North Pole, and the brightest star in the nine directions pointed by bucket handle is the symbol, and its number and orientation are exactly the same as Luo Shu. This is the so-called "nine palaces" in general techniques (Taoism takes this as the cornerstone). Among them, odd numbers one, three, seven and nine are yang, two, four, six and eight are yin and five are middle. This is the standard Luo Shu. The number of nine palaces in Luo Shu is odd, called Yang number, and even, called Yin number, called two, four and sixty-eight. Yang number is dominant, ranking fourth, representing the weather; The number of yin is supplemented, and the number of yin is at the four corners, which represents the earth's gas; Secondary five, rustic, the ancestor of the five elements, is in the middle of the palace and sends four directions. From this, we can draw three points: first. The Jiugong in Luoshu was formed by observing Taiyi's car, the Beidou bucket handle, from the four corners of the center. Two. It is pointed out that the nine palaces in Luo Shu are closely related to the changes of Yin and Yang in the Eight Diagrams. Three. This paper expounds the seasonal transformation and meteorological changes of four seasons, eight festivals and twenty-four solar terms caused by "Taiyi entering the palace". The law of numbers. So does the book "River Turow" really imply the principle of the universe? What is its content? I can only talk about Luo Shu here, that is, Nine palace map. Explain Nine palace map's figures in detail, or you can see some truth. First of all, in Nine palace map, the sum of numbers is equal to 15. I'm afraid everyone knows that the sum of horizontal, solid and oblique is equal to 15. 4+9+2 =153+5+7 =158+1+6 =154+3+8 =159+5+1= When we add the number to two digits, the sum of the left and right columns is still equal. That is 43+38+84=27+76+62. The gradual change from bottom to top still exists. That is 83+34+48=67+72+26. Three digits are still equal, that is, 438+384+843=276+762+627. Bottom-up recursion still holds, that is, 834+348+483=672+726+267. If this continues, four digits, five digits, six digits, one hundred digits and one thousand digits will still hold. Magic hasn't arrived yet. What's even more amazing is that the sum of the squares of one or two digits and three digits can be left and right equal. For example, two digits are 43 2+38 2+84 2 = 27 2+76 2+62 2. The sum of the squares of three digits and four digits can still be established. In other words, one hundred or one thousand people can be established. The magical arrangement of this number really surprised me. Then, Nine palace map is calculated by determinant method, and the number of weeks of 360 can be obtained. In front of these numbers, I can't imagine that such a number row has incredible magic. det[4，9，2； 3,5,7; 8, 1, 6] = 360 is such a nine-grid number arrangement, which solves the mathematical problem put forward by American mathematicians that the squares are strictly equal. At that time, it was a mathematical problem that no one could solve, and even the computer could do nothing. The result was conquered by Peng Shaoding, a professor of mathematics who studied Luo Shu. "Classic of Plain Questions" records: "Number theory: one is plain questions, the other is easy questions, the third is plain questions, the fourth is moral questions, the fifth is classics, the sixth is six questions, the seventh is interval questions, the eighth is life questions, and the ninth is gram questions". "Jane has water, Liuhe has land and is cold, so winter is in the north. Second, one day, seven days away from the fire, it is summer, in the south. Three roads are full of gas, eight students are flourishing, and spring lives in the East. Four virtues are successful, nine grams of gold, so autumn is in the west. The five classics have laws, and the soil is full of ten classics. After the birth of the law, the soil was rich, so I was in the middle. " Many records in Su Wen Classic are different from those in other related books. Organizers of simple classics think that what is recorded in simple classics is the most original and accurate. The name of the picture painted by Fuxi in the Classic of Su Wen is Su Wen Tu, which is the same as the gossip that people know now. Later, people added the words "look at the root of Li Zhenkun's right" and it became gossip. Simple pictures are only recorded in simple classics. The definition of river map is different from the following. Bottom line: He Tu and Luo Shu were produced through the observation of astronomical phenomena, and became valuable things for emperors in the three dynasties. Hetu and Luoshu are simple in structure and are one of the cultural cornerstones of ancient China. Liao Ping, a scholar of Confucian classics in Qing Dynasty, made many textual researches on The Book of Songs, The Book of Changes and The Internal Classic, and confirmed that the theory of The Internal Classic originated from The Book of Changes, while the mathematical theory of The Book of Changes depended on Heluo.
