The difference between six hexagrams and six hexagrams is that six hexagrams are mainly composed of five elements, and six hexagrams are equal to gods and evil spirits. Six hexagrams is the basis of six hexagrams, so the level of six hexagrams is relatively low and simple.

Six people, also known as the six-person gods, together with Taoism and Taiyi divinity, are the first of three types. As the saying goes, "people don't have to ask if they are six years old." Liu Ren has nearly 30 million pieces of information, which makes Liu Ren highly accurate in calculating the movement changes of things. It contains all the space-time relations and resonates with the laws of nature.

Six hexagons and plum blossom Yi Shu both originated from the Book of Changes, and they are two kinds of techniques evolved from the Book of Changes. Six hexagrams used the gods to grasp the ups and downs according to the sun and the moon, and used the five elements to decompose the punishment and flush the empty tomb, and analyzed and predicted what was asked; The number of plum blossoms is predicted by the relationship between body divination and divination and the image of everything.

Tracing the history of Liu Ren:

The origin of six benevolence techniques is very early, which is recorded in the Spring and Autumn Annals of Wu Yue and Yuejueshu in the Han Dynasty, and the classic of six benevolence techniques and the explanation of six benevolence instruments in the Annals of Sui Shu Classics. The title of Liu Ren is also mentioned in history books, such as Tang Shuyi Wenzhi and Song Shiyi Wenzhi.

Four lost records recorded the Great Exhibition in the Song Dynasty, and introduced the cloud-compiled Song Zhi without recording it. There are as many as 82 Liu Ren recorded in Zheng Qiao's TongZhilue. There are 89 copies of Jing Ji Zhi and 8 copies of Qian Shu Gu Tang Bibliography 18, which have been lost for a long time.

This is an example from the Song Dynasty engraving, and it is copied as before, with the preface of Six Noble Persons. The case revealed the names of six people, but its purpose was not announced at all times. However, Zhou Li Li Zhe's Book in the Palm built the nest of dead birds with the number of stars on the 10th, 12th, 12th and 28th, that is, it was not a book of three generations. This is the only proof, which is different from the saying that the five elements begin with water, aquatic and one becomes six.
