Definition
苦心 (kǔ xīn) refers to painstaking, deliberate effort — the hard work that comes from dedication and care. Unlike 大力 (dà lì), which emphasizes great force or vigorous action, 苦心 focuses on careful, often emotionally invested work. It is more positive than 刻意 (kè yì), which can imply unnatural deliberation, and less metaphorical than 心血 (xīn xuè), which specifically describes the emotional "blood, sweat, and tears" invested.
