The Shining Pearl in the Sea

"The Shining Pearl in the Sea" (Rangyayo: 海中두明珠 eyu rin tu agoju) is the national anthem of the Kingdom of Rangya. It was written and composed in the 1880s by an uncredited source, and officially adopted by the kingdom in 1910. The title comes from a colloquial sobriquet for Rangya dating to its time as a 14th-century Chinese vassal.
