Biography of Cohesion. Nine yue:
Days, drops, drops, drops, drops, drops, drops, drops, drops, drops, drops, drops, drops, drops. Five days, five digits, five combinations; There are five days in twenty, thirty places in the earth and fifty places in heaven and earth, and they become ghosts and gods.
The number of Dayan is fifty, and its use is nine out of forty. Divided into two, one like two, one like three, and the fourth like four. It's strange to jump at the age of four and then jump at the age of five, so it's divination.
What it says is:
Odd numbers: 1.3.5.7.9 are positive numbers and days.
Even number: 2.4.6.8, 10 is a negative number, which is the base.
Total number of days: 1+3+5+7+9 = 25.
Sum of places: 2+4+6+8+ 10 = 30.
The sum of heaven and earth: 25+30 = 55
Number of geese: 50.
Divination calculation: not 1, only 49.
I don't know why Dayan's number only takes 50 instead of the number of heaven and earth. So there are many different explanations for this problem from ancient times to the present.
Jing Fang of the Western Han Dynasty said:
Fifty people, that is, ten days, twelve days and twenty-eight nights, are all fifty.
Ma Rong of the Eastern Han Dynasty said:
Tai Chi gives birth to two instruments, two instruments give birth to a birthday month, four o'clock in the sun and moon, four o'clock in the five elements, five elements in December, and twenty-four gas in December, which is fifty.

Contemporary king said:
The number of big swallows should be fifty, and the number of big swallows should be five. The word "five" may have been lost in ancient books.
Others say: River Map and Luo Shu are composed of black spots and circles, with black spots representing yin and circles representing yang, which are the most basic elements of the book. Hutuluo's books add up to exactly 50 black spots and 50 circles, which means 50 yin and 50 yang.
There are different opinions, but they are not completely convinced, making "the number of big swallows" an eternal mystery.
Bucai thinks: first of all, we should use the original meaning of ancient artificial numbers instead of understanding. Arabic numerals were introduced into China at the beginning of the 20th century, and they have been popularized for more than 100 years, so they cannot be explained.
Let's take a look at the figures made by our ancestors first.
The original meaning of the word "one" is the smallest original unit and the smallest positive integer.
The ancients thought: Tao stands for one, life for two, life for three, and everything for three. In other words, the whole existence of chaos is "one" from the beginning; Then, from the chaotic "one" at the beginning, the "two" poles of heaven and earth were separated; Between the poles of heaven and earth, the "third" part of man is reborn; Heaven and earth, evolved everything in the universe.
The original meaning of the word "two":
The poles of heaven and earth separated by chaos.
The sum of one plus one.
The original meaning of "three" word creation: heaven, earth and people derived from everything.
A positive integer between 2 and 4.
The original meaning of the word "four": a positive integer twice that of two.
The original meaning of the word "five": universal elements such as gold, wood, water, fire and earth.
The largest number in the palm of your hand. Extended understanding can be the largest cardinality that a palm can grasp. Why isn't "Team" called "Team Four" or "Team Place"? That's why.
The limit number of elements representing the universe is greater than four and less than six.
The original meaning of "six" is the sum of four plus two, a positive integer between five and seven.
Open your palm and put your thumb on it, just like Oracle Bone Inscriptions's Six.
The original meaning of the word "seven": the limit number that the ancients thought needed to be divisible, namely, the number greater than six and the positive integer between six and eight.
The original meaning of the word "eight" is segmentation.
The ancients thought that "eight" was the limit number and said it was "a mess".
Everyone has two hands, four fingers and eight fingers. When the ancients counted, they all counted one by one with their fingers broken. When they count to eight, they don't count their fingers, but break their fingers and count the forks one by one. Count to eight. In normal sign language, the index finger and thumb are separated, and the tiger's mouth is facing up, indicating that eight is called eight. In ancient times, people used sign language to bargain on their sleeves, meaning that the tiger barked at eight o'clock with its mouth down. "Eight" is like a straight figure with its jaws down. Represents a positive integer greater than 7 1.
The original meaning of "nine" word-making: verb, reaching into the hole and feeling to determine the situation. An uncertain number, a limited number. The sum of eight plus one, the largest positive integer in a number.
The original meaning of the word "ten": a rope used to tie chronicles, representing all numbers and integers. An integer in the traditional mathematical system, that is, the sum of nine plus one.
In ancient times, the human hand was the oldest and most ready-made counting tool. At first, people used one hand to represent one, two hands to represent two, and five fingers to represent five, which were counted by "15 10".
Popular science digression:
Because there are only a handful, the notation of calculation and compilation was invented in Shang and Zhou Dynasties, which is also called compilation, strategy, operator and so on. It turned out to be a small bamboo stick, a counting tool, also called a chip.
There are two ways to calculate numbers: if you want to represent a multi-digit, that is, arrange your numbers horizontally from left to right, the number of numbers should be raised vertically and horizontally, the number of numbers should be expressed vertically, the number of numbers should be expressed horizontally, the number and number of digits should be expressed vertically, and the number and number of digits should be expressed horizontally.
Zu Chongzhi, an ancient mathematician in China, calculated that pi was between 3. 14 15926 and 3. 14 15927.
And quotient code count. Quotient code: Symbol representing numbers, also called Glass code. It can be understood as uppercase and lowercase numbers, such as 1.2.3 now.
Quotient code: 〡〢〣〤〥〦〧〨〩.
Chinese characters: 1234567890
Zero still drew a circle.
write
First, written in vertical rows: 〡
Two, two vertical: 〢
Three, three vertical: 〣
Fourth, it is a cross: 〤
The verb (the abbreviation of verb) is written: 〥
In fact, it is a scribble of five words.
Six, written as: 〦
One point plus one horizontal, one of which stands for "five".
7. Write a little and add two horizontal lines: 〧
8. One point plus three horizontal lines: 〨
9, written as "long" grass: 〩
Use examples
The ancients used an abacus to count. The above point is like the next child on the abacus indicating five, so 〦 is six and 〧 is seven, which is easy to understand. It should be noted that when "〡〢〣" meet, the middle will become a horizontal line. Otherwise, "|||" will not know whether it is one hundred and eleven, three, twenty-one or twelve. If you say 2 134, you should write 〢〣〤.32 and write 〣 2. (end of popular science)
According to the existing literature, heavenly stems and earthly branches existed in Archaean, in which twelve earthly branches represent twelve different months and holiday seasons every year. Ten words, such as A, B, C and D, appeared in the Shang Dynasty, which were called Tiangan, and were used in combination with earthly branches (such as Jiazi and E Yuan) to express the year, month, day and time. There is also the existence of Oracle Bone Inscriptions, 12 Zodiac. The relationship between the twelve earthly branches and the zodiac. It's just not systematized and widely promoted.
Heavenly stems and earthly branches, referred to as "Ganzhi" for short, is used to arrange year numbers and dates in the summer calendar. Ten branches and twelve branches are matched in turn to form sixty basic units. The ancients used this as the serial number of year, month, day and time, which was called "the discipline of branches and branches" and was mainly used for timing. The zodiac is used to remember the year.
Tiangan: 1 A, 2 B, 3 C, 4 D, 5 E, 6 F, 7 G, 8 X, 9 N,10 c.
Twelve earthly branches: 1, 2 ugly, 3 cloudy, 4 gross, 5 morning, 6 si, 7 noon, 8 Wei, 9 Shen, 10 you,1Xu, 12 sea.
Let's look at the earliest coins in ancient times. Five shells are a system, and two systems are a friend. And later copper coins. * * * The same point is hollowed out.
The copper coins in the outer ring are made by inheriting the thoughts of our ancestors since the time of Qin Shihuang.
In addition to being convenient to carry together, the money is invested from the inside of the outer ring. The bigger moral is that China emphasized the saying that "the sky is round and the place is round, and the outer circle is inside" in ancient times, so the ruling class incorporated this idea when minting coins, including the traditional world outlook of the ancient people in China. It is a symbol of "destiny and imperial power".
For more than 2,000 years, copper coins are all inside the outer circle, so the nickname of money is "Kong Fangge", and there is Gan Kun in "Kong Fangge".
There is not only a square hole in the middle of copper coins in China, but also a square hole in the middle of ancient copper coins in Japan and South Korea.
Why do you want to hollow it out? We can finally get down to business.
I think this is probably the reason why Dayan takes 50 out of 55 in the number of heaven and earth instead of 5.
Fuxi's gossip is "five", which represents the wind. Confucius said: Xun, enter also! That is, the air that can flow through, feng shui.
"Five" occupies the position of emperor in the Eight Diagrams of King Wen.
The "five" in the river map is the central soil.
"Five" is celebrated in the 12 zodiac. For the dragon.
"Shuo Wen Jie Zi" says: Chen, Zhen Ye!
"Interpretation of Heaven" records:
The North Pole is called Beichen.
The sun, moon and stars refer to the North Pole, and later to the North Star.
Chen and Chen are words. The original meaning of word creation is: the time when you can see the North Star and the sun at the same time.
At the end of Yin Dynasty and the beginning of Zhou Dynasty, it was said that the sky has an axis and a North Pole, which hangs over the earth and rotates.
The original meaning of the North Pole here is not the North Star, but the highest point in the sky.
Later, it was used to refer to the highest point in the sky, even the North Star.
Polaris, or crape myrtle. The Big Dipper revolves around its four seasons. If the sky is compared to a funnel, the purple star is the top of the funnel. The numerology world calls this kind of person like a "purple star surrounded by stars" the purple life. But the scope of the encirclement is large and small. Born at home is the head of the family, born in the country is the head of the family.
In ancient times, the highest point of the North Pole in the sky represented the source of the emperor, so the residence of the emperor was "Chen".
"Earthquake" can also be extended to the emperor's explanation.
"Wu" is the fifth day of the earthly branch, and it is also the homonym of "Wu". The traditional meaning of "Wu" is "Wu", which is a cognate word. The original meaning of this word is: to pay homage to the dead by dancing, and the extended meaning is: nothing.
"five" homophonic, the fifth "e"
Shuo Wen Jie Zi: Er, located in the sky. The glyph is like the interweaving of six dragons and five dragons.
"E" is also the first of the three unique and six devices of Taoism.
E, self, Geng, Xin, people, ghosts.
E: Geng Jie is fierce, fierce.
So the number of heaven and earth is five out of fifty:
Yang counted everything on the first day. For Chen, for the dragon, for the earthquake, for the son of heaven. It is the floorboard of gold, wood, water, fire and earth. Is the maximum limit. For learning, for flowing feng shui. For the invisible man. Because the pronunciation of "nothing" has no meaning. As the residence of the emperor.
Lao Tzu's "Tao Te Ching" Chapter 45 says:
Without great achievements, using them will not be harmful. If you have a big profit, you can use it endlessly.
Its original intention is: the most perfect thing looks incomplete, but its function will never fail; The richest thing looks empty, but its function is endless.
Ancient coin designers thought that "outer circle" symbolized fate and "inner side" represented imperial power. Money is made into the shape of the inner side of the outer circle, symbolizing the royal power, the supremacy of the imperial power, and the circle has square holes, representing a steady stream of Feng Shui. Where coins circulate, the prestige of imperial power spreads.
Taboo is a unique phenomenon in China's ancient society, which began in the Zhou Dynasty, became in the Qin Dynasty and flourished in the Tang and Song Dynasties. What's more, the sacred meaning is unpredictable. The son of heaven is the master of the world.
Therefore, it is considered that the number of Dayan is fifty, and the sum of heaven and earth is fifty-five. The reason for fifty-five is basically the same as the reason for the hole in the outer circle of ancient coins.
As for why we don't use the number of Dayan's fifty, we use forty-nine. The reason is similar to what Lao Tzu said.
The universe starts from scratch, from the beginning, and changes to three.
Fifty is a perfect number. The so-called heaven and earth are incomplete, and everything that shows images cannot be perfect, and everything that is perfect cannot show images.
Fifty avenues, 49 of which are the natural evolution of heaven and earth, are beyond the influence of human beings. Only the one that escaped can be interfered and influenced by human beings, so it can be called destiny and variable, and it is also a glimmer of life left by God to all beings, and the possibility of wireless.
Forty-nine is the general trend, and one is the variable.
This is my understanding.
