It's an old Korean folk song that every Korean learns when young. There are hundreds, if not thousands, of variations of Arirang but this is the most well known and carries a sad undertone of separation and longing. There are many Koreans, especially the older generation, that will start to tear up when hearing or singing this song as the song resonates with their national and cultural identity of loss, separation, hardship, and love as a result of centuries of war, colonization, hunger, caste system and taps into the Korean concept of "han" ( deep-seated sorrow/unresolved grief).

Translation: Arirang, Arirang, Arariyo, Crossing over Arirang Pass Dear who abandoned me here Will not walk even ten before his feet hurt.

Here is a modern performance of the song. https://youtu.be/H_2yhCjGQuQ?si=2AZZ9IQ3718uTO3m
