'Dōngōu' (Eastern Europe) is a geographical term referring to the eastern part of the European continent. It combines two characters: 'dōng' meaning 'east' and 'ōu' short for 'Ōuzhōu' (Europe). Unlike 'Xīōu' (Western Europe), 'Dōngōu' typically includes countries such as Poland, Ukraine, Romania, Bulgaria, and the Baltic states — though exact boundaries can vary depending on historical, political, or cultural context.

This term is commonly used in news, geography, history, and international relations discussions. It appears in both formal and general contexts — for example, when describing migration patterns, economic integration, or Cold War-era divisions. While 'Dōngōu' is widely understood, it's important to note that China’s official usage often aligns with internationally recognized regional groupings rather than strict geopolitical definitions.
