不解

not understand
❓ 不 (not) + 解 (untie/solve) = cannot untangle the meaning
Think of a knotted rope you cannot untie. 解 means to undo or solve, so 不解 is failing to unravel a problem. Sounds like 'boo-jee-eh' — boo, the answer won't come loose!
不 — single pictograph; bird flying upward
Originally a pictograph in oracle bone script, traditionally interpreted as a bird flying up toward the sky and unable to come down, suggesting negation or refusal. Over time it became the standard negation word in Chinese, used before verbs and adjectives to mean 'not'.
解 — horn 角 + knife 刀 + ox 牛
解 is an ideograph showing hands using a knife (刀) to separate the horn (角) from an ox (牛). The original meaning was to butcher or dismember an ox, which broadened to 'untie, separate, loosen,' and then extended figuratively to 'explain' or 'understand'—to take something apart mentally.
