Her family moved to Shelley Street, Hong Kong when she was ten years old. When she was eleven her father died, and she began working to support her seven brothers and sisters.

For several years she worked a triple job of telephone operator in the day, band player at night, and working as a cashier. But she also worked as a line cook for takeaway contractors for office workers, thus having excellent cooking skills, which led to her having hosted 3 food and cuisine shows.
