‘Chí zhī yǐ hénɡ’ is a classical four-character idiom meaning ‘to persevere consistently’ or ‘to persist steadily over time.’ Literally, it breaks down as: 持 (chí) = ‘to hold/maintain,’ 之 (zhī) = a pronoun meaning ‘it’ or ‘this,’ 以 (yǐ) = ‘with’ or ‘by means of,’ and 恒 (hénɡ) = ‘constancy’ or ‘perseverance.’ Together, the phrase evokes the image of holding onto something steadily, using constancy as the method — emphasizing long-term commitment rather than short bursts of effort.

This idiom is commonly used in formal or inspirational contexts — such as education, self-improvement, sports training, or career development — to praise or encourage sustained diligence. It carries a positive, earnest tone and often appears in speeches, essays, or motivational advice. Unlike casual verbs like 坚持 (jiānchí), 持之以恒 conveys deeper moral weight and classical elegance, reflecting Confucian ideals of steady cultivation of virtue and skill.
