Amos is a 2024 graduate of the Master of Arts in Music program at The Chinese University of Hong Kong, having earned his B.A. in Religious Studies (First Class Honours) in 2023 at CUHK. His classical music training began in childhood, where he studied piano and violin and participated actively in school orchestras. At university, Amos pursued vocal studies under the guidance of Mr. Caleb Woo and Mr. Irwin Chan, obtaining Distinction at the ABRSM Grade 8 Singing Examination.

Amos’s enthusiasm for choral music was ignited at his alma mater, Sha Tin Methodist College, where he was a member of the Boys and Mixed Voice Choir, Madrigal Team, Melodica Ensemble, and Music Society. Upon graduation, Amos expanded his choral journey by singing with the Chung Chi Choir and CU Chorus while being invited to perform as a guest chorister in concerts by the Hong Kong Youth Choir, City University Choir, and Hong Kong Baptist University Christian Choir. His love for choral music was further developed as an associate teacher at Sha Tin Methodist College, where he gained valuable experience in choral conducting, leading the Mixed Voice Choir in the Hong Kong Inter-School Choral Festival and the Hong Kong Schools Music Festival.

As a composer, Amos has made contributions to sacred music. In 2024, he premiered his original Cantonese church hymn, Mini Passion (小受難曲), during a Good Friday service of the Chinese Methodist Church (North Point). He continues to compose and arrange sacred choral music pieces for the Chinese Methodist Church.

Amos is currently an active member of the Toronto Mendelssohn Choir, SingFest Choral Academy, and the Chinese Methodist Church (North Point) Choir.
