What is the creative background of the song "Love Song of the West Sea"?

Love Song of the West Sea is a song written by folk artists Huang Qun, Li Haipeng and Liu Baoyuan in Longnan City, Gansu Province in the early 1990s. In order to find a way out of life, these three artists traveled to Beijing, but this time, their trip was not smooth. On the way back to Longnan, their car broke down and they had to wait by the side of the road for repair. While waiting for the car to be repaired, the three artists cooperated tacitly and sang the unforgettable Love Song of the West Sea.

This song deeply expresses a girl's yearning for a long-distance lover in Longnan, as well as her nostalgia for her hometown and praise for this magical place in Longnan.
