For a hexagram, looking from bottom to top is a hexagram, and looking from top to bottom another hexagram, these two hexagrams are a contour. We put a hexagram on the table, and from this side it is a hexagram, and from the opposite side of the table, we look at another hexagram.

The Yijing 's overturn is the hexagram formed by looking at a hexagram upside down. For a hexagram, looking from bottom to top is a hexagram, and looking from top to bottom another hexagram, these two hexagrams are a contour.

We put a hexagram on the desktop. From this side, it is a hexagram. From the opposite side of the table, it is another hexagram. When the same hexagram is seen from different directions, the hexagrams are different. Looking at it first is one image, but looking at it opposite is another image. Looking at it first is called a positive image, but looking at it opposite is called a overturning image. For example, Zhen hexagram , its overlay is Gen hexagram , and Xun hexagram is Dui hexagram.

The Yijing observing the image and playing words, and the observation and playing of the object are widely used. Let’s give an example below. The fifth line of the Daguo hexagram says that the dry poplar produces flowers, the lower hexagram is Xun, Xun is the dry poplar, the upper hexagram is Dui, and the upper hexagram is the cover of Xun, and Dui is the flower, so it is called the dry poplar produces flowers. The upper line of Feng Gua says, "Full the house, stead the house, and glimpse the house." The upper hexagram is Zhen, and Zhen is the overlay symbol of Gen. The upper line looks from the top down, which means Gen. Gen is the house, the home, and the household. It is said that , Yu hexagram , Chongmen hits the twelves, the two, three and four lines of the Yu hexagram form the Gen hexagram, and the upper hexagram Zhen is the cover of Gen, and Gen is the gate, so it is called Chongmen. , , if you have any words, you don’t believe it. The upper hexagram of the Kun hexagram is Dui, Dui is the mouth, which is the words. The third, fourth and fifth lines form a Xun hexagram. The Xun hexagram is the cover of the Dui hexagram. That is to say, the three supreme lines of the Kun hexagram are the positive and negative Dui hexagrams, one is upward and the other is downward, and the direction is different, so it is called saying something but not believing. The fourth line of Ge Gua says that changing your fate is auspicious. The second, third and fourth lines of the Ge hexagram form a Xun hexagram. Xun is the fate, and the upper hexagram Dui is the cover of Xun, so it is called changing the fate.

The famous Ming Yi in Zuo Zhuan said that he is talking to others, and saying defeat is greedy. The third, fourth and fifth lines of the Qian hexagram form a Zhen hexagram. Zhen is the word, and the lower Gen is the overturning symbol of Zhen, which means that the lower Zhen is a recoil. The directions mentioned are different, which is called defeated words, and positive and reverse shock is greedy.

Yi Lin’s difficult speech is contrary to the heart and words. In the hexagram, Kan is the heart, and the three supreme lines are the right hexagram, Dui is the word, so it is called the mind and the word. Kun Zhili talks about Qilu disputes. The second to fifth lines of the Li hexagram are the main ones. Dui is the word, Xun is Qi, and Dui is Lu, so it is called Qi and Lu.

The regular image of the Book of Changes is often inconsistent in actual use. The regular image can be used to cover the image, and the overlap image can also be used to cover the image. For example, the first line of the Book of Changes , Suihexagram, , said that the official has the same. The first line Zhenxiang is the image of Gen, and Gen is the official. When the fifth line first arrives, it is the right cover Gen, and the image covers the meaning of cover. Therefore, we pay attention to experience it in our study of the Book of Changes.
