砥
U+7825 "砥" CJK Unified Ideograph-# is a Chinese hanzi that primarily means "whetstone" or "grindstone," referring to a stone used for sharpening tools and knives. By extension, it carries metaphorical meanings of "to polish," "to refine," or "to temper," often used in classical and modern Chinese literature to describe the process of self-cultivation or the honing of skills through effort and perseverance. This character is composed of the radical for "stone" (石) and the phonetic component "氐," and it appears in various Chinese and Japanese texts, including idioms like "砥礪前行" (dǐ lì qián xíng), meaning to forge ahead with determination.
