/kloc-The Book of Changes in October/February is called

It is called "twelve hexagrams", also known as twelve information hexagrams, and it is an important theory in the study of Zhouyi. The theory of twelve hexagrams in the Book of Changes has a long history. It is reported that there are twelve hexagrams quoted in Gambao's annotation. In other words, it should belong to the same era as Zhouyi. The real formation of a set of theories was handed down through the arrangement of China's ancient ancestors, which is the so-called "Twelve Messages".

In a hexagram, yang is stubborn and yin is stubborn, which is called "elimination"; Yin and Yang are called "rest". Twelve information hexagrams are considered as the changes of "Gan" and "Kun". "Monarch" means monarch, and here it means domination. Twelve hexagrams are used to match twelve months, and each hexagram is the Lord of January, which means "twelve hexagrams", that is, December hexagrams. These twelve hexagrams are: Fu, Lin, Tai, Dazhuang, Bi, Gan, Bi, Bi, Wu, Guan, Pi and Kun. In the order of earthly support, the months belong to the Lord in November, December, June, June, February, March, April and May.

Among the twelve hexagrams, the hexagram handed down from Confucius to Mitsuki, and the position of the hexagram gradually rose from the beginning: the first hexagram was the first hexagram, and the neighboring hexagram was the first hexagram, the second hexagram. On the other hand, from divination in the afternoon to divination in Haikun Moon, the yin hexagram rises in turn, while the yang hexagram falls in turn, from divination to divination, the initial hexagram is replaced by the yin hexagram, from divination to divination, denial, observation, stripping and even Kun hexagram. Among the twelve divinatory symbols, Zi Yue (winter solstice of Qi) is a complex divinatory symbol, which means that Yang is born after the winter solstice, and Wu Yue (summer solstice of Qi) is a summer solstice, and Yang rises and falls, while Yin Sheng (first divinatory symbol is yin).
