The algorithm of Wenwanggua is more detailed than that of yarrow.

1. 49 yarrow trees were randomly divided into two piles. Each hand is responsible for a pile.

2. Take the small finger seam between the left hand and the right hand. (Only use the left hand to build a strategy, which is the method of Guo Yong and others, symbolizing a natural person; Zhu fa only takes one side of the right hand stake, symbolizing that life is born on the ground; Both methods make sense. I think the ancients paid attention to the relationship between heaven and man, so they tended to Guo Yong's method)

3. Take four pieces in your right hand and pile the remaining yarrow with your left hand until the number of the remaining yarrow is 1, 2, 3, 4; Then, count the yarrows piled by the right hand with the left hand until the remaining yarrows are 1, 2, 3, 4. The sum of the remaining yarrow numbers in the left and right piles can only be 4 or 8. Let's call this sum the sum of remainder.

4. Put the yarrow taken out in the second step and the left and right piles of yarrow together, so that the sum of the three parts of yarrow can only be 5 and 9. This sum is also called remainder sum.

5. Repeat the process of 1-4 for three times, and get the sum of three remainders (please note that the second and third times don't go through the fourth step, that is, it's not yarrow). Such as 5, 4, 4; Or 9, 8, 8; Or 5, 4, 8 and so on. (This is called returning to strangeness. Zhu et al. Are singular in every change, while Guo Yong and others. It is singular in the first change. Flexibility. To be exact, Zhu thinks the plan he came up with is called Xu, so we don't break it down here, but put it together.

6. Define the sum of three remainders as the remainder. Define (49- sum of complementary strategies) as positive strategy number. The quotient obtained by dividing the positive strategy number by 4 can only be 9 (pure yang), 6 (pure yin), 7 (less yang) and 8 (less yin), and this quotient can be determined.

7. Repeat the process of 1-6 for 6 times (= 18 change) and get 6 hexagrams, which become one of the hexagrams in Zhouyi.

8。 Use this divination to find divination words.

The process is explained as follows:

The number of big swallows is fifty, and its use is nine out of forty:

Big research number 50, use 49. Because only with "forty-nine" roots can the remainder be "thirty-six, thirty-two, twenty-eight, twenty-four", and only with four roots can we get "9678". From this, it is deduced that nine is the dry policy and thirty-six is the dry policy; Six for Kun Yao and twenty-four for Kun Ce.

Divide one into two, like two, hang one like three, like four: divide one into two, there are forty-nine strategies, two hands like two, left hand like the sky, right hand like the ground, like two instruments. Those who' hang one' are still hanging, and take a strategy from the left hand and hang it between the little fingers of the right hand. People who are "like three" are like three talents because the strategies they hang are in line with heaven and earth like people. "Four for one" and "four for him" also count, that is, the right-handed strategy is put in one place first, the left-handed strategy is put in one place with four or four for the right hand, the left-handed strategy is put in one place, and the right-handed strategy also has four or four for the left hand. Those' like the four seasons' are all four, that is, like the four seasons. "("She Snakes ")

Returning to strangeness is like a leap, and then leaping at the age of five, so it is necessary to hang strangeness: "strangeness" is one of the things hanging, and it is the remaining strategy for left and right hands. It is strange to symbolize leap year in the calendar; Two feet are five, so it is "five years old". Say it again: two. Symbolizes two leap months in five years.
