Where is the gossip? What does gossip heavenly stems and earthly branches stand for?
Standard, an ancient instrument for measuring time, calculated the time and solar terms by measuring the shadow of the sun, and worked out the calendar according to the measurement results. At the same time, the original patterns and concepts of yin-yang fish were also obtained. From the rise and fall of yin and yang, three hexagrams were formed, such as yang = dry, yin and yang = tan ... and then evolved into gossip.
The five elements originally did not refer to five substances, but also originated from the astronomical calendar. The five elements of Guanzi are divided into five seasons (five sections) at the age of one. Refers to the five running states of the sun in a year or a harvest season. Lu's Spring and Autumn Annals directly refers to the five elements as "five qi", which means dividing a year into five seasons. Another example is Zuo Zhuan? 6? A.D. 1 Zhao recorded that the year was divided into four seasons and five sections in turn. Where's the pipe 6? "1 five elements" says that "the five elements should be established to suit the weather". It can be seen that the five elements are only related to the weather at that time, that is, the five elements and five seasons. The only purpose of "establishing five elements" is to set the season, which means to set the season. "LingShu? 6? 1 there is "five elements in order, four points at four o'clock" in the five chaos. It can be seen that in ancient times, the five elements were interpreted as festivals or solar terms.
Some people may find it hard to understand. Since there are four seasons in a year, why do you have to divide the five elements again, that is, five seasons? In fact, this is a question of origin, that is to say, it is the arrangement of four seasons throughout the year, with five o'clock first and four o'clock later, so it is confused by later generations, just like the situation in which the lunar calendar and the solar calendar are used together today.
The Yi calendar takes 36 days as a month and 360 days as a year. Ten months end, and the other five days (or six days) are "New Year's Day". Five days in a normal year and six days in a leap year every four years. In this way, the average of four years is 365.25 days, which is almost the same as 365.2422 days in the tropical year (solar year). There are five seasons in a year, which are represented by earth, copper, water, wood and fire. The first season is divided into male and female (or male and female, respectively, January native male, February native female, March bronze male, April bronze female, May water male, June jellyfish, July wooden male, August wooden female, September fire male and October fire female. This is the October solar calendar, which began in the Xia Dynasty, also known as the summer calendar, and is the source of the ten-day dry in ancient times.
The earth originated in December of the lunar calendar, and the lunar calendar originated from the monthly ritual activities in December of the ancient lunar calendar.
With the collision and integration of various civilizations, the October solar calendar withdrew from history, and only its quality was preserved in the new lunar calendar. Later generations attached the theory of five elements to the study of calendars and monthly orders, which, like the emperors' calendars and monthly cards of later generations, are necessities of daily life.
Because the calendar is widely circulated among the people, it has become a common knowledge background and ideological framework of the people, and it is a common model of almost all knowledge categories. It is also the theoretical basis of China's traditional view of the universe and history, from which ancient philosophy, physics, chemistry, mathematics and medical skills all originated. Taoists will also use the five wonders of Taoism: mountain, medicine, fate, physiognomy and divination. As for putting forward the unity of heaven and man, it is not the credit of Taoism.
After explaining the source clearly, I will answer your question again. Do five lines of gossip and heavenly stems and earthly branches belong to Taoism or to the astronomical calendar in ancient China, that is, five lines of gossip and heavenly stems and earthly branches are closely related to astronomical calendars. The theory of Yin and Yang has a substantial basis for the existence of astronomical phenomena, and Taoism has been carried forward in some academic fields.
From the origin, five lines of gossip heavenly stems and earthly branches belongs to the astronomical calendar.
