Origin: Originally depicted a large basket or container filled with burning materials or pine wood used to illuminate paths or signal in ancient times, combining the 'fire' radical with the phonetic sound 'jù'.
Semantic Evolution: Over time, it shifted from physical fire-holding baskets to any hand-held torch, and further into literary metaphors for enlightenment and revolution (e.g., 火炬 'fire torch').
Ancient Chinese beacons and night patrols relied heavily on primitive torches ('jù') made of resinous wood.
