What do you think of those Jiazi and Jiazi of Guiguzi in Ding Jing?

Ten days of work: A, B, C, D, E, Ji, G, Xin, people, ghosts. Twelve earthly branches: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.

As early as 2697 BC, when Huangdi, the ancestor of China, established the country, heavenly stems and earthly branches ordered the brain to explore the qi of heaven and earth and the five elements (water, fire and earth in Jin Mu), which started the ten-day work of A, B, C, D, E, Ji, G, Xin, Ren and Gui, as well as Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei and Gui.

In China calendar, the time for the moon to orbit the earth once (29.5306 days) is January, and the time for the earth to orbit the sun once (365.438+09 days) is one year. In order to make the average number of days in a year consistent with the number of days in tropical years, a leap month is set up. According to records, in the 6th century BC, China began to use the method of 19 seven leap months to coordinate the lunar calendar with the solar calendar.

Heavenly stems and earthly branches is a symbol designed to keep 60 decimal places in the calendar. For ancient China people, the existence of heavenly stems and earthly branches was as simple as Arabic numerals. Later, these symbols were applied to maps, directions and time (time axis and space axis), so these numbers were given more and more meanings.

The ancients (Yellow Emperor) observed Wang Shuo's moon and found that the two moons were about 59 days. 12 months is generally more than 354 days (similar to the length of a tropical year), so the ancients got the concept of 12 months in a year. In the collocation diary method (ten-day dry), the yin-yang calendar came into being and developed in heavenly stems and earthly branches; It should be more mature in Xia, Shang and Zhou Dynasties.

Heavenly stems and earthly branches, referred to as Ganzhi for short, is used to arrange the year number and date in the summer calendar.

Calendars use heavenly stems and earthly branches to arrange year numbers and dates. There are ten words in Tiangan, so it is also called "Ten Dry". The order of arrangement is: A, B, C, D, E, Ji, G, Xin, Man and Ghost; There are twelve characters in the earthly branch, arranged in the following order: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai. Among them, A, C, E, G and E are dry in the sun, while B, D, G, G and G are dry in the shade. Zi, Yin, Chen, Wu, Shen and Xu are the Yang branches, while Ugliness, Mao, Si, Wei, You and Hai are the Yin branches.

When the trunk and the ground branch are matched, the trunk begins with nails, the ground branch begins with children, and the trunk is opposite to the branch, and the trunk is opposite to the branch (the trunk doesn't match the branch, and the trunk doesn't match the branch) to get a 60-year cycle. It is called "Sixty Jiazi" or "Flower Jiazi". In the past, China people used to mark the year, month, day and time with a cycle of 60 years.

Heavenly stems and earthly branches's 22 symbols are intricate and orderly, full of harmony and regularity. It shows the laws of natural operation, real-time (time) space (orientation) interaction, and the results of yin-yang interaction. China calendar contains the thought of Yin-Yang and Five Elements and the law of natural circulation.

Year: each branch lasts for one year. After sixty branches, it starts from the beginning and continues. Starting from Jiazi, it is called Jiazi or Huahua Jiazi 60 years later. It's called the chronology of cadres and branches.

Month: the first month begins in the shade, and the branches of the earth are fixed in each month, and then they are combined with the heavenly stems in turn; From the first month to the third month of the first year, February is Ding Maoyue and March is Chen Wu. From Jiazi month to Guihai month, there are sixty Jiazi, which is exactly five years.

Day: From the day of Jiazi, in order, the 60th day happens to be the cycle of trunk and branch.

Time: Starting from Jiazi, but the punctuality branch is fixed, twelve hours a day.

It originated from the observation of astronomical phenomena in ancient times and is a "river map"

The river map and Luo Shu produced by astronomical observation became precious items of the emperors of 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, and the mathematical theory of The Book of Changes was taken from Heluo.

The river map consists of five elements, five elements, yin and yang, and the image of heaven and earth. The schema takes white circles as yang, sky and odd numbers; Black dots are shade, ground and even number. The five elements are combined with heaven and earth, and the five elements are combined with yin and yang, so the schema structure is distributed as follows:

One and six live in the north, because they are born with water and the land is 60%; Two and seven are friends who live in the south, because the earth is inflammatory and the sky is 70%; Sanba lives in the East as a friend, because the sky is full of trees and the land accounts for 80%. Four and nine live in the west, because the land is four and gold is born, and the sky is 90%; Five and ten are in the same place and live in the center, because they were born in five places, and the land is 100%. The river map is drawn according to the five-star season. Five stars, called five latitudes in ancient times, are five planets in the sky. Wood is called the old star, fire is called the twinkling star, earth is called the town star, gold is called the white star and water is called the morning star. The five elements run, with 28 dormitories as the boundary. Because its orbit is not far from the sun road, the ancients used it to mark the sun. These five stars usually appear in the Arctic sky in the order of wood, fire, earth, gold and water. Each star has a line of 72 days, and five stars are 360 degrees in a week. It can be seen that the river map is drawn by the five-star sky, which is also the source of the five elements. Because mercury can be seen in the north before the winter solstice of 1 1 month every year, when the winter weather comes, everything is dormant, and there is only snow and water on the ground. This is how the concept of water travel was formed. After the summer solstice in July, Mars appeared in the south, and the ground was very hot in summer weather, so the concept of fire line was formed. At the vernal equinox in March, Jupiter appeared in the east, and just as spring came, plants sprouted and grew. The so-called "spring comes to the world to know flowers and trees", and the concept of wood walking is formed in this way. In September and the autumnal equinox, Venus appears in the west. In ancient times, it represented weapons in many ways to show that the autumn war was just at that time, and everything was old and withered, which made Venus come into being. Saturn was seen in the sky in May, which means that the air in wet soil is at the right time in the long summer, and both wood fire and golden water take this as the midpoint. Observing the four seasons climate change brought by wood fire and gold water from the ground, the concept of soil tour is formed in this way.
