Career
Tang started her singing career in the music group Cookie Girls. The main style of music from Cookies was teen pop. When Tang started her solo singing career, her record company, EMI, wanted a change to a more grown-up look and style. Some songs on her first album, Coloring Stephy, had a more mature and soft jazz influence than her previous music in Cookies. Generally, the album was widely heard and was popular, and it was certified Gold by IFPI Hong Kong. Tang's second solo album was Fantasy. The album had a total of five editions. One was a deluxe edition which contains a DVD featuring her music videos from this album. The only difference between the other four was the color themes of the album covers: red, yellow, blue, and green, which were four different themes for photo shoots. Her third album is Dating Stephy. This album also features different covers, and a special edition was released three months after the original release. The album also sold as well as her previous two. There was no official announcement of the certification, as Gold Label Entertainment Ltd and EMI Music Hong Kong did not participate in IFPI Hong Kong. However, the newspapers announced that Dating Stephy has sold over 30,000 in one month, and it was at least Gold certified. In 2007, she performed at the S.U.C.C.E.S.S. Charity Gala at Vancouver, British Columbia, Canada with many other artists. Tang performed her first headline solo concert, called "Stephy, See Thru Live 2007".

She also did a Mandarin version of "Breaking Free" from High School Musical with Anson Hu. Tang released her new album The Red Album in November 2008. Some tracks in this album, such as "女兒紅", have led to media attention on the improvement in Tang's voice. In July 2009, Tang published her first romance novel, Running Alongside Me. The book takes the form of a diary about a girl who has recently broken up with her lover. She goes on a cruise and writes about the things she sees and does. This book also includes 100+ pages of photos, making it a photo book as well. In December 2009, Tang released her collection of "Greatest Hits" plus "New Songs" songs in a 2CD+ DVD Collection called 'Music Cafe' which includes four new songs, including Running Alongside Me, which served as the same name as her novel.
