He formed the band Wu Bai & China Blue with Dean Zavolta (drums), Yu Ta-hao (keyboards), and Chu Chien-hui (bass guitar).

His father was a retired Taiwan Sugar Corporation worker and his mother a betel nut vendor, and he had two younger brothers who died in a car accident.

His nickname Wu Bai, meaning "five hundred," was given to him by his neighbours, after his early academic success when he scored 100 points on each of five examination subjects when he was studying at primary school.

[2] Dean Zavolta describes the formation of Wu Bai & China Blue noting that the members originally "played for different bands up until about 1991, after which [Chu Chien-hui] and I began jamming together with the eventual idea of forming a newer, fresher, and original rock band ... Then one day, he called me up and asked me if I would mind filling in for a one-off gig with himself and a guitarist named Wu Bai ... Something just clicked between us.

Based on this increasing popularity, Wu was given a contract with Rock Records' Mandala Works, which released his second album Wanderer's Love Song and accompanying music videos.

[5][6] In June 1998, after representing Taiwan Beer in its new television commercial, Wu also appeared in a Chinese movie A Beautiful New World, playing the part of a street singer.

After these phenomenal successes, Wu sang at Taiwan's new president's inauguration, Singapore's National Day concert, and Japan Fukuoka's Music Festival.

Wu listened to 1970s English-language rock music such as Led Zeppelin and Jimi Hendrix in his formative years and has said he felt it unusual for a Taiwanese person to play the guitar.

The band's distinctive blend of poetical lyrics with rock tunes has won them fans not only in Taiwan but throughout East and Southeast Asia and they have had successful regional concert tours in the many cities.

Wu is an avid fan of Japanese pro wrestling, and has even written a theme song for his close friend, Keiji Mutoh.
