How to get started if you want to learn Qimen Dunjia:
1. The day of Rujie Festival happens to coincide with the head of the Shangyuan Talisman. The ancients called it "zhengzhi", which is rare.
2. The Shangyuan talisman arrives earlier than the solar terms, which is called "Super God". It is more common when the time and solar terms alternate.
For example: (1995) The Spring Festival begins at 3:24 pm on the fifth day of the first month of the lunar calendar. On this day, the daily stems and branches are Bingyin and the head of the symbol is Jiazi. The stems and branches on the third day of the first month before the beginning of spring are Jiazi. , starting from the third grade of junior high school, he went to the eighth game of Yuanyang in the beginning of spring. This is called "super god".
3. The solar terms are in the front and the Shangyuan Futou is in the back. This is called "receiving Qi".
For example (2002), the beginning of spring occurred on December 23rd of the Xinsi year of the lunar calendar. This day was Guimao, which was not the talisman needed for the beginning of spring and the new year. By Jiyou, the tenth day of February in 2002, There are only ten talismans needed for the Li Chun Shangyuan, so from the day of Jiyou, the Li Chunyang Bureau Shangyuan talisman is used.
In the alternation between symbol heads and solar terms, there are more Shangyuan symbol heads in front of solar terms and less in behind solar terms. The gap between them is sometimes only one or two days, and sometimes it is more than nine days. When the head of the Shangyuan Talisman exceeds nine days, a leap will be placed.
To set a leap, that is, on the last day of this solar term, repeat the upper, middle and lower three elements of this solar term from the Shangyuan. If you repeat this for fifteen days, what was originally a super god will become " "Connecting Qi", the Shangyuan Fu head has reached the back of the next solar term.
There is a rule for placing leaps. Only the two solar terms of Mangzhong and Daxue can be placed. The purpose of setting leaps is to adjust the correspondence between the twenty-four solar terms and the upper, middle and lower three elements of Qimen Dunjia, so as to Keep A and Ji's daily stem and branch as the talisman, so that the bureau of Shijia Qimen can be determined from the daily stem and branch talisman.
In addition to the leap method, there are two other methods. One is the extension method created by Maoshan Taoist, which starts directly from the junction time of each solar term, using the Shangyuan Bureau of this solar term, Shangyuan It takes sixty hours to transfer to the Zhongyuan, and the Zhongyuan uses sixty hours to transfer to the Lower Yuan.
