“By the Butterfly Spring” is an interlude song from the romantic comedy film “Five Golden Flowers” produced by Changchun Film Studio in 1959.

The movie told the love story of a pair of Bai youth who made promise of love through antiphonal singing by the butterfly spring in Dali, Yunnan. At that time, the unique tradition of Bai people expressing love through antiphonal singing was still quite unfamiliar to other Chinese ethnics.
