Break (2005–2007) In 2005, Cheng had only one feature film release and no music projects. She became a representative for Veeko and Titus, a fashion and watch brand in Hong Kong, respectively. She also began writing Saturday columns for Mingpao magazine. In 2006, she released another greatest hits album, but there were no new tracks.
