The song comes from Avatar: The Last Airbender, where Iroh sings it in the Tales of Ba Sing Se episode as a quiet memorial to his late son, Lu Ten. Originally a simple folk tune within the show, it became one of its most remembered moments after fans shared the full scene online and quoted its gentle melody in tribute edits. Its association with remembrance, rather than a joke or trend, has kept it in circulation for years, especially in videos honouring people, characters and moments that viewers do not want to forget.
