In 1971, she graduated from high school and began to perform at the Qingquangang American Army Club (CCK) in Taichung with Yingying Huang and they became friends.
Before becoming a singer, Su Rui wanted to be a physical education teacher.
At that time, she was good at track and field and basketball, so she hoped to be a teacher and teach students.
Her song "The Same Moonlight" (一樣的月光; 1983) first propelled her from an unknown to a singing sensation in Taiwan overnight when it was released in 1983.
She is also known for her hit "Any Empty Wine Bottles For Sale" (酒矸倘賣無), the widely popular soundtrack to the Taiwanese film Papa, Can You Hear Me Sing.
