The word 打卦 is formed by combining the verb 打 (dǎ), meaning "to strike" or "to hit", with the noun 卦 (guà), which refers to the divinatory hexagrams used in practices such as the I Ching. Literally, it signifies the action of striking or manipulating divination blocks or lots to generate a hexagram, thus denoting the act of performing divination. The term directly reflects the physical process involved in this traditional method.
