After a brief hiatus, she changed her name to Emme and returned with her second album (self-titled) in 2003, marked by a new, more mature playgirl image, and uptempo dance tunes which she has been noted for ever since.

In addition, album [The Groove in Me] was highly complimented by Andy Lau and Hacken Lee, and Emme has been named by Alan Tam to be the special performance guest for his ten consecutive concerts in Hong Kong.

In 2006, Emme acted in a national education movie of "A Chinese Fairy Tale" with one of the Best Actor Awards' winners, Tony Leung Ka Fai, for the first time in Beijing.

On the other hand, Emme composed lyrics for her song "Cruel" which became popular because of the touching wordings, and its ringing tone stood in the top download charts for several months.

To commemorate the return of Hong Kong 15th anniversary (1997–2012), "Management World" of the Beijing authorities held an election of "Bauhinia Merit", Emme and other 54 outstanding & successful Chinese entrepreneurs were elected and compiled into a book, in recognition of their excellence in industrial and commercial achievements, as well as the contribution to the economic and social development in Hong Kong and Mainland China.
