In ancient times, fortune-telling was done by grass. What does it look like? Can you describe it?

Choose fifty, choose one without, and use forty with nine. Divide this into two parts at will, take one from the right hand and hang it between the little fingers of the left hand; From the number of yarrow on the left, every four, the rest (just over four is the remainder) are between the little fingers of the left hand; Count the yarrow on the right again, every four, and combine the rest between the little fingers of the left hand, which is "one"; Then put the remainder between the little fingers, then put the yarrow of the left and right numbers together, divide them at will, and take one from the right and hang it between the little fingers of the left hand; Do it again as above, and put aside the one taken from the right before combining the residues on both sides with the residues of "one", which is called "two"; Play yarrow from left to right again as above; This is "three". The number of yarrow left after "three rows" must be one of the four numbers of 24, 28, 32 and 36. Divide by four to get four numbers of 6, 7, 8 and 9, where 6 and 8 are yin, 8 is static and 6 is dynamic; 7, 9 is yang, 7 is static and 9 is dynamic. Three changes are the beginning of success.

According to the method, 49 yarrows will be repeated, and three will become two.

30% hexagrams, one hexagram becomes six hexagrams, so there are eight diagrams in ten hexagrams.

Think for yourself! Take a good look!
