Following the birth of her son and almost a year's hiatus from music, Tse released a new songs and greatest hits compilation, "3/8", in December 2007. The compilation's three new songs, "3/8", "Zhong Wu Yan" (鍾無艷) and "The Retired Life of Wonder Woman" (神奇女俠的退休生活) were all released as singles, with the latter two reaching number 1 on various charts. Tse explained that the album title, "3/8", refers to the eight stages of life, and the three-eights that she has traveled. This refers especially to her musical life, summing up her musical journey in the past three years.
