When she was an undergraduate, she serve as an arranger, a music director and singer in Mosaic. She kept her passion in a cappella and took her another identity (being a member of SiS) as an advantage to further promote a cappella music to the public. By holding different scales of a cappella workshops and teaching more than 10 primary and secondary schools, more students fall in love with a cappella music.
