比利时冷知识：欧洲的心脏，布鲁塞尔

Together with Washington D.C., Brussels has the highest number of diplomats and foreign press correspondents in the world. Since the end of the Second World War, it has been a major centre for international politics and the home of numerous international organisations, politicians, diplomats and civil servants. Brussels is the de facto capital of the European Union, as it hosts a number of principal EU institutions, including its administrative-legislative, executive-political, and legislative branches (though the judicial branch is located in Luxembourg, and the European Parliament meets for a minority of the year in Strasbourg) and its name is sometimes used metonymically to describe the EU and its institutions.
