This tricolor flag originated from Germany's 19th-century democracy and unification movements. It signifies emerging from the darkness (black) through bloody battles (red) to reach the golden light of freedom (gold).

Germany is a country with a history of the fall of the Berlin Wall and reunification, and this flag is a symbol of that. If you're a K-pop fan, you can use this emoji to show friendliness when going to a concert in Germany or interacting with German friends.
