What did China say in ancient times? Thank you.

In ancient China, years, months and days were marked by branches, that is, every day, every month and every month, there was a branch assigned to it.

The trunk is heavenly stems and earthly branches's floor. Match the order of branches, a week is 60, and repeat the record, which is also commonly known as "branch table". The ten symbols of A, B, C, D, E, Ji, G, Xin, Ren and Gui are called Tiangan; The twelve symbols of Zi, Ugliness, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai are called earthly branches.

The formula of the method of pushing and discharging cadres and branches every month is: the year of Jiaxu is the first, and the year of B Geng is the first. Bing Xin began to look for Geng at the beginning of the year, and Ding Ren was in the downstream position. Say what you have, and you can pursue it above the good news.

Extended data

1, monthly dry formula: monthly dry = annual dry x2+ months (and greater than 10, directly take single digits).

If it is known that 2008 is the year of Wuzi, then it is July and the number of months is 7, then Shen Yuegan = E *2+7=5*2+7= 17, the unit is 7,7 7= G, and Shen is the year of Wuzi.

2. Annual expenditure formula:

(Two digits at the end of the year-11)-12 * n = annual expenditure (applicable to the 20th century, that is, 1900- 1999).

(two digits at the end of AD +5)-12*N= annual expenditure (applicable to 2 1 century, i.e. 2000-2099).

For example, stem in 2030 =0-3+ 10=7= G, branch in 2030 = 30+5-12 * n = 35-12 * 2 =1=
