What does Wu Jiari mean?

China, Japan and Japan are the 3rd1day in the national official calendar.

The day before Wu Jiari is Guisi Day, and the day after Wu Jiari is B. In the five elements of Yin and Yang, the first part of heavenly stems belongs to Yang's wood, and the afternoon of earthly branches belongs to Yang's fire, which is the combination of wood and fire. Yin Na's five actions during the Wu Festival were gold panning in the sand.

China, Japan and Japan are the 3rd1day in the China calendar. In the ancient calendar of China, A, B, C, D, E, Ji, G, Xin, Man and Ghost were called "Ten Heavenly Stems", while Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai were called "Twelve Earthly Branches". They cooperate with each other in a fixed order, with a total of 60 pairs of combinations, forming the chronology, calendar, chronology and calendar.

It is said that the calendar of Shang Dynasty is the greatest achievement of the Ganzhi calendar and the longest used calendar in the world. From February of the third year of Lu Yingong in the Spring and Autumn Period (720 BC) to the third year of Xuantong in the Qing Dynasty (A.D. 19 1 1), people have known it exactly, and there are documents to prove it.

Calendar year, calendar month, calendar day and calendar time are also the basis of ancient magic numbers in China, such as Yuan Hai Zi Ping and San Tong Ming Hui. Japanese trunk branches are the centers of four pillars. Without Japanese trunk branches, China's ancient skills would be gone.

Heavenly stems and earthly branches's application fields:

1, calendar era

Branches are mainly used in the calendar era. The original branch is "social body", also known as "Tai Sui". Tai sui meets in A, is blessed in B, gentle in C, and strong in Ding Yue; Take photos of Teague in Yin Yue, Mao Yue and Chen Yue. (The language is "Erya Shi Tian"). This set of chronological history books has far-reaching influence, and later generations will use it in calendar, arithmetic, calculation, naming and so on (Zi Tongzhi Jian, the official history book compiled in the Northern Song Dynasty, is based on this set of official terms).

In the process of inheritance and development, later generations simplified this set of dating terms into a one-word name. The original names of the main branches in Erya and Historical Records are compared with those of the simplified main branches.

2, ordinal number, rating and classification

After the main ordinal function of heavenly stems and earthly branches was replaced by numbers such as one, two, three and four, people still used it as a general ordinal number. In particular, A, B, C and D are not only used to list classified articles, but also used to rate and classify things in daily life. In the nomenclature of organic chemistry, the compounds with 1- 10 carbon atoms are named after Rhizoma Dryopteris, such as methane (1 c atom), ethane (2 c atoms), propane (3 c atoms) and so on.

3, science, medicine, feng shui, Shu Shu and numerology.

In the theory of Yin-Yang and Five Elements, branches are divided into Yin and Yang, odd numbers belong to Yang and even numbers belong to Yin. A, C, E, G and N in the heavenly stems, and Zi, Yin, Chen, Wu, Shen and Xu in the earthly branches are yang numbers; The heavenly stems of B, D, Ji, Xin and Gui and the earthly branches of Ugly, Mao, Si, Wei, You and Hai are all negative numbers. On this basis, according to the theory of mutual restriction, the harmony, rise and fall, conflict and its birth and death of personnel are calculated.
