Hò khoan Lệ Thủy singing is a Vietnamese folk music style characterized both by its antiphonal nature, with alternating groups of female and male singers issuing musical challenges and responses, and by the fact that most of the songs in the repertoire deal with topics of love and sentimentality as experienced by young adults. Hò khoan Lệ Thủy originated from Lệ Thủy District, Quảng Bình province, Bắc Trung Bộ, Vietnam. Local residents used to sing hò khoan when they work in groups so that it would help them eliminate tiredness and speed up the productivity. Nowadays, hò khoan is just used in local festivals and original songs have somewhat faded away.
