树立 (shù lì) is a verb meaning 'to establish' or 'to set up'—especially abstract things like authority, confidence, ideals, or a positive image. Literally, 树 means 'tree' and 立 means 'to stand,' so the original imagery evokes planting and making something stand firm, like a tree taking root and growing upright. This metaphorical sense emphasizes intentionality, stability, and lasting influence.

The word is commonly used in formal, written, or inspirational contexts—such as speeches, education, leadership training, or policy documents. It often appears with objects like 信心 (xìn xīn, 'confidence'), 权威 (quán wēi, 'authority'), 形象 (xíng xiàng, 'image'), or 目标 (mù biāo, 'goal'). It implies active effort and conscious cultivation—not passive occurrence—and carries a positive, constructive connotation.
