Fung started writing creatively in secondary school. After her postgraduate studies at Columbia University, she returned to the University of Hong Kong to teach translation and contemporary literature. She co-founded and edited a number of literary journals. Bian Zhilin's poetry sparked her interest in modern poetry, and she began to translate poetry into English after moving to Canada in 1994. She also translated works by Hong Kong writers including Wu Yin-ching and Wong Leung-wo.
