Chronology of Gengshen's annual trunk and branch

The year of Gengshen is a year in the long history of China. The combination of "heavenly stem" and "earthly branch" is adopted in the year of dry branch; "Tiangan" is a, B, C, D, E, G, Xin, man and ghost; The earthly branches are Zi, Ugliness, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai. Match A, C, E, G and Ren in the Ten-day trunk with the sub-cycle, Yin, Chen, Wu, Shen and Xu in the Twelve Earthly Branches, and then match B, D, Ji, Xin, Gui Chou, Mao, Si and Wei in the Ten-day trunk to get sixty combinations. Twelve earthly branches are combined with twelve kinds of animals: rats, ugly cows, yinhu, maotu, dragons, snakes, afternoon horses, sheep, monkeys, pheasants, dogs and porcupines; Every year, a group is regarded as the "Zodiac" of that year, and everyone born in that year takes this "Zodiac" as his "Zodiac"; It circulates every twelve years. Geng Shennian is the Year of the Monkey, and people born in this year are monkeys.

The so-called chronology of dry branches means that dry branches are literally equivalent to trunks and branches and leaves. In ancient China, the sky was dominant and the earth was subordinate. The connection between the sky and the trunk is called heavenly stems, and the connection between the ground and branches is called earthly branches. Together, it is called heavenly stems and earthly branches, or "dry branch" for short. The ancients in China used these 60 pairs of branches to represent the serial numbers of years, months, days and hours, and this is the chronology of branches.

The chronology of cadres and branches began in beginning of spring in the twenty-four solar terms, and the chronology of cadres and branches is the calendar chronology of cadres and branches. The same is true of the official almanac (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 a 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. The year of Gengshen is one of the sixty years in the official calendar, and the corresponding Gregorian calendar years are 1920, 1980, 2040...(60-year cycle).
