The Danube is the second longest river in Europe, second only to the Volga River in Russia, and also the most important international river in Europe, with a total length of 2,857 kilometers, a drainage area of 810.7 million square kilometers and an average flow of 6,500 cubic meters per second.

Originated in the Black Forest region of Germany, it flows through Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, Ukraine and other 10 Central and Eastern European countries. It is a river that flows through the most countries in the world and finally flows into the Black Sea from the Danube Delta.

The Danube River basin also includes nine countries including Poland, Switzerland, Italy, Czech Republic, Slovenia, Bosnia and Herzegovina, Montenegro, the Republic of Macedonia and Albania, with more than 300 tributaries.

As can be seen from the map, a section of the Danube is the boundary river between Romania and Moldova, so it flows through Moldova. This view, Baidu Encyclopedia and Wikipedia are different. The map proves that Wikipedia is right. This is my opinion.
