Alec Su's career started in 1988, at the age of 15, when he joined the Little Tigers trio. The band was the first idol singing group that debuted in the Taiwanese music industry and Alec was labelled as the "obedient tiger." The group's popularity was unprecedented; the Little Tigers attracted fans from Taiwan, Hong Kong, China, Singapore, and amongst Chinese communities around the world. The success of the band began the new generation of Taiwanese pop culture in the early 1990s. In 2010, the Little Tigers were invited to participate in the CCTV Spring Festival Gala, in which they sang a medley of three of their biggest hits and won accolades as the "favorite singing group" for the event.
