Xin Weinian's Chronology of Cadres and Party Branches

The so-called calendar year of trunks and branches means that trunks and branches are literally equivalent to trunks and branches. In ancient China, the sky was dominant and the earth was subordinate. The connection between heaven and stem is called heavenly stem, and the connection between earth and stem is called earthly branch. Together, it is called heavenly stems and earthly branches, or "dry branch" for short.

The chronology of cadres and branches begins in beginning of spring with 24 solar terms, and it is the chronology method of the calendar of cadres and branches. The same is true of the official almanac of past dynasties (that is, the Yellow Calendar). After the Republic of China, the emperor's year number was abandoned, and the lunar calendar can only record the year with dry branches, which ranges from the first day of the first month to New Year's Eve, which is indisputable. Lunar calendar and trunk calendar are two different calendars, which are different in the starting point of a year, the division rules of months and the number of days in each year. Due to the use of the Gregorian calendar after the Republic of China, many people lack the knowledge of the calendar, so the two are often confused.

There are ten heavenly stems, namely A, B, C, D, E, Ji, G, Xin, Ren and Gui, and twelve earthly branches, namely Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai. The earthly branches correspond to mice, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and pigs in the Chinese zodiac. The ancients put them together in the order of Jiazi, Ugly B and Bingyin (that is, the sky turns six times and the earth turns five times, which is just a cycle). Sixty pairs from Jiazi to Guihai are called Jiazi. Xin Weinian is one of them.

Among the sixty jiazi, Wei Xin and Geng Wu are roadside soil, and the five elements belong to soil. Also known as goats and local sheep.

The ancient Chinese used these 60 pairs of branches to represent the serial numbers of year, month, day and time, and this is the chronological method of branches. The replacement of cadres and branches shall be subject to beginning of spring.
