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. "Wedding Invitation Street" and rise to prominence (2008) 2008 was a watershed moment for Tse's music career. Her first single of the year, "17 Degrees" (17度) topped three of the four major singles charts, with second single "Wedding Invitation Street" becoming the most well-known song of 2008 (囍帖街). "Wedding Invitation Street" was released amidst controversy over the redevelopment of Wan Chai's Lee Tung Street, from which the songs takes its title. Although appearing to be a love song about letting go on the surface, many have read it as a potent critique on the city's urban renewal plans. The song made a lasting impression on Hong Kong's collective consciousness, and marks Tse's rise to prominence as not only one of the leading female singers of Hong Kong music, but also as a socially conscious "grassroots diva". Both "17 Degrees" and "Wedding Invitation Street" were released on the album Binary in July, to overwhelming critical and commercial success. The album was certified platinum, with sales exceeding thirty-thousand copies. Tse swept all the most prestigious year-end music awards in 2008, including the Media Grand Prize co-presented by Hong Kong's four major media outlets awarded to the performer garnering the most awards that year. In November, Tse was admitted to hospital for suffering Pneumothorax, which was reportedly the fourth time the condition had occurred. This had impacted her ability to sing with Tse being hospitalised for a week. Yelling and Slowness, HKRIA controversy (2009) Following-up on the previous year's success, Tse released two albums, Yelling and Slowness in 2009. The former was released on 19 March, which spawned two hit singles "Zhu Ying Tai" (祝英台) and "Song of the Year" (年度之歌), further establishing her popularity. She announced her first stadium concert, Kay Tse Yelling Live 2009 in support of the album, which was held at the Hong Kong Coliseum in May. The concert later toured to Macau and Guangzhou
