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 in December, becoming her first concerts held outside of Hong Kong. In fall 2009, HMV Hong Kong announced that "Yelling" was the 9th biggest selling album of the year, which sold in excess of 15,000 copies, rivaling long established female acts such as Joey Yung and Miriam Yeung.
