Character by character
Origin and story
Political metaphorThe Book of Documents, 'Pan Geng, Part One,' compares spreading unrest and misleading talk to a fire sweeping the open country, beyond easy approach or extinguishing. This passage supplies an older image of dangerous expansion, but it does not contain the exact four-character expression or its initial spark.
An exact Qing attestation appears in Yan Youxi's Shu Hua Sui Bi, where a small fire spreading across the plains illustrates why beginnings require care. Modern usage can also be hopeful, describing a small movement growing into a powerful force. Whether the spread is welcome or alarming depends on the context, not on the metaphor alone.
In everyday life
最初只有几个人参加的社区互助，如今已有星火燎原之势。
The community mutual-aid effort began with just a few people and is now spreading rapidly.
A small beginning developing into a large force; can describe beneficial growth or dangerous escalation.
