Also known as predetermined destiny, one of the fortune-telling techniques based on time. This technique is not like the general time fortune-telling technique that combines the stems of year, month, day, and hour into four pillars and eight characters. Instead, it only uses the year pillar and the hour pillar to match the two heavenly stems at the beginning and end of the hour pillar, so it is called the Lianghui Clamp. For example, if a person was born in the Renzi period on the Bingwu month, the Dingchou day of the Jiazi year, only the two characters "Jiaren" and "Jiaren" can be used to predict the fate. In this way, if the ten heavenly stems match each other one by one, there will be one hundred pairs, that is, one hundred destiny patterns. Under each grid, first determine the nature of the hexagram position. Under the hexagram position, if the hour stem is yang, take the six earthly branches of Zi, Yin, Chen, Wu, Shen, and Xu. If the hour stem is yin, take Chou, Mao, and Si. There are six earthly branches: , Wei, You, and Hai. There is a four-character idiom inscription under each earthly branch, implying good or bad luck in the three years. Secondly, there are six eyes: Lezki (ancestral property), Kunyu (brothers), Xingzang (experience), marriage, inheritance, and retirement. Under each eye, there is a meaningful seven-character quatrain as a symbol of their respective destiny. assertion. Thirdly, a four-character idiom is used to point out the fate of the person who is being calculated, and a five-character or seven-character rhyme poem is attached, which always talks about numerology. Finally, a vernacular short essay is used to describe the rise and fall of the person's personality, virtue and foolishness, and destiny. Make a conclusion. This technique claims to be the first of its kind by Gui Guzi, but the quatrains and rhymed verses of the Spring and Autumn Period in which Gui Guzi was active have not yet appeared, so it is not credible. This technique is still spread in a few areas.
