She grew up in a foster home with her brother Sid but was adopted by Mei Wa who she calls Nana along with Sid and Tobey. She works along with her brother and best friend at Wu's Garden as a delivery girl. When Kong Li schemes to destroy the barrier that keeps him trapped inside Chinatown she fights to thwart his plans.
