How it is used
- To be glad/willing to do something - 乐于助人 (lèyú zhùrén) happy to help others (a set praise phrase); 乐于分享 (lèyú fēnxiǎng) glad to share.
- Followed directly by a verb; conveys taking genuine pleasure in the act, more positive than plain 愿意 (yuànyì, willing).
- 乐 is read lè ('happy') here, not yuè; 于 = 'to/in'.
