How to Write 崆 (kōng) — Meaning “mountain cave; hollow”

Imagine a mountain (山) with a big empty space (空) inside it—like a hollow cave. The sound kōng is the same as 空 (empty), so you can think "kong mountain = empty mountain cave." This visual and sound link makes it easy to recall both the shape and meaning.

Keep the left radical 山 narrow and balanced, while the right part 空 should be slightly wider. Be careful with the stroke order of 空: write the top 宀 (roof) first, then the bottom 工. A common mistake is making the 山 radical too wide or misaligning the two parts vertically. Practice the hook at the top of 宀 to avoid a flat shape.

Unlike 崆 (hollow mountain cave), 峇 is rarely used alone and appears in place names like 峇里 (Bali), while 峋 means 'steep' or 'sublime' and often pairs with words like 嶙峋 (rugged). Visually, 峇 has 合 (combine) inside, and 峋 has 旬 (ten-day period) inside, whereas 崆 has 空 (empty). Their meanings and pronunciations are distinct.

崆 appears almost exclusively in proper nouns, especially place names like 崆峒山 (Mount Kongtong), a famous Taoist mountain in Gansu. It is also part of 崆峒 (Kongtong), the area around the mountain, and 崆岭 (Kongling), a mountain ridge. You will rarely see it in daily conversation, but it is important for geographic and cultural references.

Common words containing 崆 include: 崆峒山 (kōng dòng shān) — Mount Kongtong; 崆峒 (kōng dòng) — Kongtong; 崆岭 (kōng lǐng) — Kongling.
