When to use it
衷心 (zhōngxīn) literally means 'from the heart/core'; so 衷心感谢 is heavier than a casual 谢谢. You'll see it in speeches, wedding toasts, farewell cards, and LinkedIn-style thank-you posts. Don't use it for small favors like someone holding a door; Chinese speakers find that overdramatic. Save it for genuine gratitude: a mentor who changed your career, a friend who helped through an illness. In a WeChat message you might even add 🙏 emoji. The grammar point: 衷心 functions as an adverb describing *how* you thank.
