流亡 (liú wáng) literally combines 流 (liú), meaning 'to flow' or 'to drift', and 亡 (wáng), meaning 'to perish' or 'to flee'. Together, they convey the idea of being forced to leave one’s homeland and live abroad—often for political, religious, or ideological reasons. It emphasizes involuntary displacement and a loss of homeland, not voluntary travel or migration.

This word carries strong historical and political connotations and is commonly used in formal contexts: news reports, biographies, historical accounts, and human rights discussions. While it can function as a verb ('to live in exile'), it also appears as a noun ('a person in exile' or 'exile' itself). Unlike neutral terms like 移民 (yí mín, 'immigrant'), 流亡 implies persecution, danger, or threat at home, and often suggests an intention to return once conditions improve.
