"Huang Ji Jing Shi" was written by Song Dynasty scholar Shao Yong. In "Huang Ji Jing Shi", Shao Yong woven a huge historical chronology, which revolves closely around the innate sixty-four hexagrams. Shao Yong analyzed the corresponding relationship between the position of the 64 hexagrams and the time, and believed that the beginning to the upper yao represented different time and space, and the specific situations of these different time and space were all captured by the hexagrams formed after the changes of each line. And pointed out that the relationship between this line position and the time inclination has profound philosophical implication. He created a new unit for measuring time, which he called "Yuan, Hui, Yun, and Shi". The year 129600 is one yuan, a development cycle of mankind. Twelve meetings per yuan, 10800 years each. Thirty lucks per meeting, 360 years each. Every twelfth generation, 30 years each. There are hexagrams in Yuan, Hui, Yun, and the world, and every year there are also hexagrams to indicate changes in astronomy, geography, and personnel development.
Shao Yong compiled a grand chronology of the history of the universe according to time units. He took the innate sixty-four hexagrams and circle diagrams as the starting point for the hexagram change, and brought in natural history and human history, expressing his heroic cosmic feelings and strong humanistic concerns. According to Shao Yong, the development cycle of human civilization is 129,600 years. After that, the earth entered the ice age, life was reborn, and human civilization was revived again. Repeatedly, endlessly. In this Yuan, the birth and death of civilization strictly follow the sixty-four hexagram circle diagram he drew. One yuan has twelve guilds, and the four hexagrams of Qian, Kun, Kan, and Li are used first. To be more specific, the three guilds of Li Gua will report the Zi, Chou, and Yin; the Qian Gua will take the three meetings of Mao, Chen, and Ji. Kan Gua dominates the three meetings of Noon, Wei, and Shen. The Kun Gua governs the Three Meetings of You, Xu and Hai. Every time there are two solar terms, then these four pure hexagrams each have six solar terms, for a total of twenty-four solar terms.
Leaving hexagram moves at the beginning of the line, changes the travel hexagram to the winter solstice, the second line moves, and the big hexagram becomes small cold; the third line moves, the biting hexagram changes to the big cold; the fourth line moves, and the pen hexagram changes into spring. The movement of the five lines changes the hexagram of the same person into rain; the movement of the upper line changes the hexagram of Fengfeng into a startling sting. Shao Yong believes that all things happen in this thrilling solar term, that is, when the Lei Huo Feng Gua is the time of the season. That is what he said "open things here." The ninth day of the first day of Qianchu changes the Mei Gua, which governs the vernal equinox; the second line changes the same person, the main Qingming, the third line changes the foot, the main rain, the fourth line changes the small animal, and the main start of summer. The movement of the five lines becomes large, and the main part is small; the movement of the upper line changes to the center, and the main mang species. Kanchuyao changes section, dominates the summer solstice, the second line changes change ratio,The main office. The three lines change well, the main department; the four lines change into trouble, the main start of autumn; the five lines change, the main place is heat; the upper line changes, the main white dew. At the beginning of the Kun, the line changes and reverts, the autumn equinox is the mainstay, the second line changes the division, and the cold dew is the main line; the third line changes, the main status descends. The four lines change to hesitate, dominate Lidong.
Five lines of dynamic transformation ratio, the main light snow; the upper line of dynamic and peeling, the main heavy snow. The extinction of all things is in the frosty solar terms, that is, when the three lines of the Kun Gua move, and the time when the Qian Gua's value is changed. Shao Yong said, "The closed things are here" In this chronology of the universe's history, according to calculations, we are now in the "Summer Solstice", which is dominated by the Jie Gua formed by the movement of the Kan Gua at the beginning of the line. From these four pure hexagrams, we can see that Shao Yong’s hexagrams change from the beginning of the line to the top, and one line represents an era. But he is not satisfied with this. In order to have a more detailed insight into future changes, he has formulated other sixty hexagrams, so that he can observe the changes in 2160, 360, 60, 10, and 1 year. First of all, he made the sixty-four hexagrams of innate hexagrams. He took out the four hexagrams Gan, Kun, Kan, and Li, and the remaining sixty hexagrams were allocated in the time of one yuan.
Don't use these four hexagrams. As Wang Zhi said, "Except for those who do not use the Qiankun Likan Sizheng hexagrams, they must not be used, and they can be used as run hexagrams." One yuan has 129,600 years, so the time allocated for each hexagram is 2,160 years. There are twelve guilds in one yuan, namely Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai, so each meeting is governed by a total of 5 hexagrams.
