How to Write 吂 (máng) — Meaning “ignorant; unaware”

Imagine a person opening their mouth (口) but nothing comes out because their mind is 'lost' (亡) — they are ignorant and have nothing to say. This visual of a silent, blank mouth helps link the components to the meaning of being unaware.

Write the top radical 口 as a narrow rectangle, with the bottom stroke closing fully. Then draw 亡 below: start with a dot on the left, then a horizontal stroke, then a vertical 'L' shape — make sure the final vertical stroke does not extend below the foot of the 'L'. A common mistake is making 口 too wide or connecting the two parts too closely.

吂 (máng) means 'ignorant', while 卟 (bǔ) is rare and mostly used as a phonetic character in ancient Chinese, and 古 (gǔ) means 'ancient' or 'old'. Visually, 吂 has 亡 below the mouth, 卟 has 卜 (divination), and 古 has 十 (ten) under the mouth — each lower part gives a distinct meaning.

吂 is very rare in modern Chinese and not part of the HSK vocabulary. It appears mainly in classical or literary expressions like 吂不知 (totally unaware) and 吂然 (blankly) to describe ignorance or a dazed state. You may encounter it in older texts or poetry, but it is almost never used in everyday conversation.

Common words containing 吂 include: 吂不知 (máng bù zhī) — totally unaware; completely ignorant; 吂然 (máng rán) — ignorantly; blankly; 吂吂 (máng máng) — ignorant; muddled.
