扰乱 is a verb meaning 'to disturb' or 'to disrupt' — it describes an action that breaks order, peace, or normal function. The first character 扰 (rǎo) means 'to bother' or 'to disturb', often implying unwanted interference; the second character 乱 (luàn) means 'chaos', 'disorder', or 'confusion'. Together, they form a compound verb emphasizing the *causing* of disorder — not just passive disturbance, but active disruption of systems, processes, or environments. It’s commonly used in formal and semi-formal contexts: news reports, official notices, classroom instructions, or discussions about public order.

This word often appears with objects like 秩序 (order), 教学 (teaching), 会议 (meeting), or 网络 (network). It carries a mildly negative connotation and usually implies responsibility — someone or something is actively causing the disruption. Unlike milder terms like 打扰 (to bother), 扰乱 suggests a more serious or systemic interruption, sometimes with consequences.
