How do sixty-four hexagrams divide yin and yang?
Sixty-four hexagrams are divided into yin and yang. Fang Jing has already discussed this point:
Yang divination: Gan, Yi, Bi, Wu, Xun, Xiao beast, Ke, Yi, Gen, Ben, Da beast, Loss, Kun, Fu, Pro, Tai, Zhen, Yu, Jie, Heng, Hui, Kun, Cui, Xian, Kan, Kun.
Yin hexagrams: viewing, peeling, gold, being big, naive, gnawing, eating, squatting, walking, crouching, gradual, being big and strong, squatting, needing, comparing, rising, um, biggish, following up, being modest, being small, being younger, and reforming.
How to distinguish the yin and yang of the sixty-four hexagrams can be found in the names of the hexagrams.
The name of Yigua is messy at first glance, but it is not without traces. There are some special words in the names of hexagrams, such as Tai, Wu, Ding, Feng, Jin, Kun, etc ... These symbols are symmetrical and mirror images of the middle line. Ambigrams is not uncommon in Chinese characters, such as gold, wood, water, fire and earth, but it seems to be used a lot in the sixty-four hexagrams. According to a preliminary count, there are 15 species of Thai, leather, Ding, Dui, Ben, Xu, Jin, Kun, Cui, Jing, Feng, large livestock, small livestock and bronze man, which is quite a lot.
The hexagrams named after symmetrical glyphs also have a common feature, that is, they all deviate from yin and yang and belong to a group of neutral orientations.
Among the sixty-four hexagrams in the Book of Changes, half are symmetrical hexagrams with names, which belong to neutral areas, and the other half are asymmetrical hexagrams with names, which belong to non-neutral areas. It is not difficult to distinguish whether they are positive or negative. The composition of the sixty-four hexagrams completely conforms to the law of combining yin and yang. The laws of symmetry in nature are everywhere. It has been stated in the Book of Changes.
