Depicted as a sweet innocent cartoonish character in promotional materials, Guo grew wide recognition within weeks of her debut single release.
Her two music videos reportedly cost near to $250,000 to shoot, filmed by top Taiwanese director Lai Wei-kang.
Guo was the first artiste to be granted legal copyrights to sing "Mice Love Rice" outside of China; the resulting hit single was the first to make it to the top of Singapore's RIAS sales chart in 2005.
For Singapore's 2006 May-Day concert, she was invited to perform alongside other big Singaporean stars such as Stefanie Sun in front of a crowd of 20,000.
[9] Her second single, No More Panic, a Chinese-language cover version of Dragostea Din Tei by O-Zone, was released in early November 2005.
The album contained new songs and covers that range from catchy mid-tempo tunes to acoustic folk and sentimental numbers.
