📖 Meaning
To delve deeply and thoroughly into a subject, penetrating to its innermost core. It describes a rigorous, introspective approach to analysis or self-cultivation, leaving no layer unexamined.
📜 Origin Story
This idiom originates from a letter written by Zhang Shi (张栻), a prominent Neo-Confucian scholar of the Southern Song dynasty, to his friend Hu Jisui (胡季随). Zhang lamented that while some students of his era were willing to pursue learning, few could endure the sustained effort required. He urged them to '鞭擗向里' — meaning to whip and split their way inward — stressing that only through such relentless self-scrutiny and deep inquiry could one truly recognize their own shortcomings and make genuine progress in moral and intellectual cultivation.
💡 Example Usage
做学问要鞭擗向里，不能浮于表面。
In pursuing scholarship, one must delve deeply into the core and not merely skim the surface.
