Rosemary was composed by Jay Chou and written by Fang Wensheng. Chopin in November, published by Jay Chou in 2005, was criticized for no breakthrough and no change. In 2006, when preparing for the album Still Fan Texi, Jay Chou changed his style and broke through the previous route, creating a jazz-style song Rosemary. He also tried to sing sexy when recording. Vincent fang wrote the lyrics of this song with the idea that "the fragrance of rosemary describes the charm of women".
