Hsu is also an accomplished lyricist. Her lyric-writing talent first gained serious notice when she completed several songs for Taiwan's R&B singer-songwriter Jay Chou. By proving that she is not just another pretty idol, but a very capable artist, Hsu surprised both her critics and adorned fans. She continued to collaborate with Jay on his second and third albums after his triumphant self-titled debut, and co-wrote songs for other pop performers, such as Leehom Wang, Vanness Wu, Show Lo and Gigi Leung. Her lyric work is much praised for its clever and straightforward simplicity.
