鼓舞 (gǔ wǔ) is a stronger, more formal way to say 'to inspire' or 'to boost morale,' often used for spiritual or collective motivation (e.g., inspiring news, morale). Unlike 鼓励 (gǔ lì, HSK4), which is everyday encouragement for specific actions, 鼓舞 conveys a profound, uplifting effect. It borders on 振奋 (zhèn fèn, HSK7) but focuses more on the act of inspiring than the resulting state of excitement.
