集中 (jí zhōng) is a verb meaning 'to concentrate' or 'to focus' — especially attention, effort, resources, or people toward a single point or goal. The character 集 (jí) means 'to gather' or 'to collect', while 中 (zhōng) means 'center' or 'middle'; together, they literally convey the idea of 'gathering into the center'. This word emphasizes directed, intentional unification — whether it’s mental focus during study, physical gathering of people for an event, or strategic allocation of funds.

It’s commonly used in both formal and everyday contexts: in schools ('集中注意力' — 'focus your attention'), workplaces ('集中精力完成任务' — 'concentrate energy to finish the task'), and public announcements ('请集中到礼堂' — 'please gather in the auditorium'). Unlike more casual synonyms like 专心 (zhuān xīn), 集中 often implies purposeful coordination or consolidation, not just personal attentiveness.
