重塑 (chóng sù) is a verb meaning 'to reshape' or 'to reconstruct' — literally 're-' (chóng) + 'to mold/shape' (sù). It emphasizes deliberate, often effortful transformation of something’s form, structure, or function, especially after damage, decline, or obsolescence. Unlike simple verbs like 改变 (to change), 重塑 implies rebuilding from within, restoring integrity or purpose.

This word is commonly used in formal and semi-formal contexts: medical rehabilitation (e.g., reshaping body function after injury), corporate strategy (reconstructing brand identity), education (reshaping learning methods), and personal development (reshaping habits or self-image). It carries a positive, aspirational connotation — suggesting renewal, resilience, and intentional growth rather than mere alteration.
