Her debut studio album, Jade-1, containing 11 tracks, was released July 3, 2002. She achieved her first number one hit on RTHK and TVB's Jade Solid Gold Song Chart with the song "You Have Heart" 你有心, released in her second studio album Jade-2 on December 20 of the same year. Both Jade-1 and Jade-2 reached gold certification, selling 30,000 copies and 50,000 copies respectively. As such, Kwan was awarded 2002 IFPI Best Selling Local Female Newcomer.

This sparked controversy with TVB, as the act was considered a breach of contract. Subsequently, all artistes under BMA Records management were banned from appearing on TVB programmes, which at the time was considered an important medium. Jade made a public apology, stating, "I am a TVB contract artiste, perhaps the company [BMA Records] was negligent... I hope TVB will be lenient". More controversy ensued when an internet rumour spread in November 2004, known as "My Sister Got Fired" (家姐被炒潮文), in which Kwan supposedly gotten a retail sales representative fired. Kwan repeatedly stated the story was false; however, her popularity decreased significantly. It also earned her the nickname "Sister Kwan". 2009–2010: Shine and A New Beginning After her contract with BMA ended in May 2009, Kwan focused her efforts on recording a Christian album. Shine was released under Jade Star Limited on September 21, containing 12 tracks. Kwan signed with Stars Shine International in 2010 and returned to the charts with the single "Starting Over", a Cantonese version of Liu Liyang's "Present". Her album A New Beginning was released October 11, 2010. A second single, "Try Love Personally" was released to critical success, with Kwan being praised for her vocal ability. She won Top 10 Song at the 33th RTHK Top 10 Gold Song Awards;
