😤 FAN blowing on a hot STOVE = agitated and restless
Fán sounds like fan, zào sounds like stove. A fan rattling against a hot stove captures that fidgety, can't-sit-still irritation. The character 烦 means vexed, 躁 means restless — vexation plus restlessness equals jittery.
烦 — fire 火 + page/head 页
烦 combines 火 (fire) with 页 (head), depicting a feverish or burning head. The original sense was a headache caused by fever, which extended metaphorically to mental distress, irritation, and being bothered. Today it commonly means annoyed, troublesome, or vexed.
