At the age of 19, at the outbreak of the war against Japan, Sen-Yong moved to Yongding county in Fujian, where he was a teacher of arts, music and gymnastics at the Yongding Provincial Middle School. A year later he attended the National Fujian Academy of Music, majoring in vocal music.
In 1946, Sen-Yong was appointed as music teacher at the Hsinchu Junior High School. Sen-Yong's music was selected to become the official school song, accompanying lyrics written by school principal Hsin Chih-Ping . In the 1960s and early 70s Sen-Yong led the Hsinchu School Choir to many repeated championships of the province-wide chorus competitions, and also directed the Taipei Women's Normal High School Choir. He retired in 1973 from Hsinchu Senior High School.
After spending several years residing in Brazil, Sen-Yong returned to Taiwan where he continued to be active in the music world as the conductor of the Industrial Technology Research Institute Chorus and the Hsinchu Science Park Chorus, and also being honored for his musical contributions through concerts and compilations of his chorus compositions.
Sen-Yong was diagnosed with Parkinson's disease. He died at the age of 88.
Most of Sen-Yong's compositions were written for the choruses that he conducted over the years. But he has also composed for the piano and for a string quartet.
In 1967, under the influence of Professor De-Yi Liu , german composer Paul Hindemith, and the traditional chinese five-notes scale, Sen-Yong was able to create a more distinctive and modern style.
