A lot of people know that the French language of fries is "Chips", which the Americans call "French Fries". In fact, its real source is belgium. As early as 1680, Belgians began to make this kind of potato chips, [1]. In the first World War, American soldiers ate this kind of French fries in Belgium, and they became so popular that they became popular. But they took it for granted "French" because the common language in the Belgian army was French, and they thought it was "French fries".
