This hexagram is named "Shi He," meaning to bite or chew. It reveals the principle that the use of punishment must be based on confirmed laws, be clear and decisive, and apply both leniency and severity. This embodies the early Chinese thought on the rule of law. In the hexagram's imagery, the first and top lines represent lips, the second, third, and fifth lines represent teeth, and the fourth line represents an obstacle between the upper and lower teeth that must be bitten through for closure, hence the name "Shi He." The hexagram's shape resembles food within a mouth, as if about to be chewed, thus it is named "Shi He."
How does biting and chewing relate to punishment? There are several possible explanations. Wang Bi states, "Shi means to gnaw. Gnawing refers to punishment and subduing." According to Wang Bi, "Shi" can be used to refer to punishment and subduing. Therefore, "Shi" can be seen as a pun or metaphor, simultaneously referring to biting an object and the application of punishment. While ancient I Ching scholars' interpretations may differ slightly, their general arguments do not deviate from Wang Bi's framework.
Chen Guoying believes that "Shi Zhe Jue Ye" means that Shi He is the process of resolving and reuniting, which refers to the execution of criminal law. This view can also be referenced. Another modern scholar proposes that the hexagram Shi He tells a story about eating meat violating etiquette and receiving punishment, deriving the meaning from the second line, "Eating flesh, one loses one's nose." Obtaining this hexagram in divination extends to an image of obstacles and harm to benefits. Furthermore, thunder represents unexpected disasters. With Li (fire) above and Zhen (wood) below, fire burns wood, and wood generates fire. The lower trigram, Zhen (wood), will be completely consumed by fire. Therefore, this hexagram also symbolizes a beautiful and attractive outer appearance (Li fire) that continuously depletes inner energy and savings, extending to the meaning of consuming one's resources without replenishment.
