How to interpret divination with three variables?

There are sixty-four hexagrams in the Book of Changes, and each hexagram consists of six painted hexagrams, all of which are heavy hexagrams, that is, two three painted hexagrams, the upper three painted hexagrams are external hexagrams, and the lower three painted hexagrams are internal hexagrams. Each painting is called a position, and each position is a positive position or a negative position. When drawing hexagrams, draw from bottom to top, followed by the first hexagram, the second hexagram, the third hexagram, the fourth hexagram, the fifth hexagram and the last hexagram. The first is the beginning, the sixth is the end, the sixth is the top, the first is the bottom, and the last is the top and the bottom is the beginning. This is to express the meaning of the first and sixth hexagrams.

Yang is nine and Yin is six. Why is Yang nine and Yin six? In the river chart generation number, one two three four five is the birth number, the birth number is the beginning of all things, one three five is a positive number, which adds up to nine, and two four is a negative number, which adds up to six, so Yang is called nine and Yin is called six. There is another saying that among one to ten numbers, odd number is Yang, even number is Yin, Yang is moving, Yin is stable and motionless, and nine is the largest odd number and the most moving number, so nine represents Yang, and six represents two, four, six, eight, ten, and five even numbers, which is the most stable and average, so six represents Yin.

The ancients believed that from bottom to top, odd digits were Yang (one, three, five) and even digits were Yin (two, four, six). It is both right and right that the yang is in the yang position and the yin is in the yin position, and vice versa.

According to different kinds of things, the six figures can be divided into different images. As far as social class is concerned, the first represents the countryside, the second represents the cities and counties, the third represents the provincial government (municipality directly under the central government), the fourth represents the position of minister, and the fifth represents the position of monarch (emperor). The three seats above represent the central departments, and the three seats below represent local administrative regions. The sixty-four hexagrams of the Book of Changes are mainly things of the way of monarch and minister, so they are used a lot in this respect. If it represents human body parts: one represents feet, two represents legs, Theory of Three Represents thighs, four represents waist and chest, five represents neck and chest, and six represents head. Among the three hexagrams, the top is the sky, the bottom is the tunnel, and the middle is the person. Of the six hexagrams, the upper two are the sky, the lower two are the tunnels, and the middle two are the people. People are between heaven and earth, and they are born by grasping the yin and yang of heaven and earth.

Among the six hexagrams, the heaven above and the heaven below are born together, the person above and the person below are born together, and the place above and the place below are born together, which means to seek for the same spirit, to respond in unison and to intersect with the same kind.

One, four, two, five and three correspond, one yin and one yang correspond, and two yang or two yin do not correspond or are called enemy reactions. 25 is the middle, and the middle is more important than the right. Take the middle one first, then the right one.
