You are snowing heavily in the sunny days in the south, and I am blooming in the cold nights in the north. The meaning of this lyric is that it seems absurd when it is sunny and snowy, and it is like spring in the long night, but it pushes the pain of parting and inner contradictions to a climax through absurd scenery. Finally, the inner pain is beyond words, and the strong unresolved sadness is also dispersed.

As one of Ma Di's representative works, Nan Shannan is a blend of poetic talent and melodic talent, with a sense of poetic vicissitudes. Words and expressions are touched by notes and instrumental music, and they sing a feeling of sadness, frustration and confusion. The tune is composed of guitar, piano and violin. Using the samples in Four Seasons Song and the children's voice at the end of the song, the song is made into flashback memories and fixed old photos.
