What is the origin of sixty flowers in China?

Sixty Jiazi is the earliest and greatest invention of Han nationality. The oldest usage is calendar year, calendar month, calendar day and calendar time. Calendar year is 60-year cycle, calendar month is 5-year cycle, calendar day is 60-day cycle, and calendar time is 5-day cycle.

Who is the inventor of cadre and branch discipline? Although there are the following statements to verify the origin of the main branch, who invented it? When did it first appear? This is always a mystery. It is said that the inventor of heavenly stems and earthly branches was a troublemaker in the ancient Xuanyuan period four or five thousand years ago. Archaeological findings show that in the late Shang Dynasty, Di Yi (the 30th king of Shang Dynasty) carved a complete 60 Jia Zi on an Oracle bone, which may be the calendar at that time. This also shows that in the Shang Dynasty, the dry calendar was already in use. According to textual research, there was a solar eclipse in Lu Yingong during the Spring and Autumn Period (February 10 BC). This is the exact evidence of China's use of Ganzhi Chronology, and the Emperor Year in the period of Emperor Wu of the Han Dynasty was the first year of construction. Heavenly stems and earthly branches Sixty Jiazi In the ancient calendar of China, A, B, C, D, E, Ji, G, Xin, Ren and Gui were called "ten heavenly stems", while Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai were called "twelve earthly branches". The ancient Han people used heavenly stems and earthly branches to represent the year, month, day and time. The year, the month and the day are like four pillars supporting the building of "time", so they are called four pillars. Heavenly stems and earthly branches Theory formulated by the ancient Han people should be based on observation and practice, rather than the concept of behind closed doors. For example, acupuncture in traditional Chinese medicine pays attention to the circulation of meridians, and the selection of points is regular at different days and hours, which conforms to heavenly stems and earthly branches's law.

Ten-day dry and twelve-branch cyclic combinations: Jiazi, Emei, Bingyin ... until returning to the sea, there are 60 combinations, called Sixty Jiazi, and so on. Year, month and day are all 60 cycles. 60 is a wonderful number in the field of time. Not only did the ancient Han people in China take 60 as the cycle, but in the western time-keeping method, one minute is 60 seconds and one hour is 60 minutes. Is it just a coincidence? Similarly, a 24-hour day in China corresponds to a traditional day of 65,438+02 hours (1 hour is a big hour and 2 hours is a big hour). China takes a five-day one-hour cycle, and the so-called "five-day waiting" is 60 hours in total.
