📖 Meaning
To trace something back along its course of development in order to find its root cause or origin. It describes a methodical approach of investigating things by following the path backward to where they began, much like walking upstream along a river to discover its source.
📜 Origin Story
There is no single classical source text for this idiom. It is formed from the natural metaphor of traveling against a river's current to find its headwaters. The phrase appears in later scholarly and literary usage as a variant of the synonymous idiom 溯流穷源, both conveying the idea of exhaustive investigation by retracing the course of events. The imagery draws on the universal human experience of following a waterway to its origin, making it an intuitive metaphor for scholarly inquiry and root-cause analysis.
