text: When Lee first returned to Hong Kong to attend middle school, her Cantonese was not perfect and she was sort of rustic.  At age 15, Lee was accidentally discovered by a television director, , during a school dancing performance.  She was recommended to play a role in a television series Fatherland.  Since the series did not require too much of her time and she could still study at school, her parents agreed to let her act.  In the series, she was a country girl by the name of A Mun, who looked just like Lee.  Ever since then, people liked to call her A Mun.  Her performance in the series was so impressive that she began her career as an actress.  Since she has been practicing dances from her childhood, it was easy for her to perform action movies with her agile and flexible movements.  After her first martial arts movie in ancient costumes (Zu Warriors from the Magic Mountain), she has not left the stage of action movies.
  At 18, after graduating from high school, Lee signed contracts with both Asia Television and Golden Harvest. When she was sent to Japan to make an advertisement for Mitsubishi, the company asked her to pick an English name, and she chose "Moon" as the pronunciation of Mun in Cantonese is close to the English word, Moon.
  She played in many television series, exceeding 400 episodes.  Subsequently, she focused her efforts wholly on movies, mostly action movies.  In the late 1990s, she gradually left the movie field and was passionately involved in the promotion of the art of dance and established a dancing school to cultivate talented dancers. Her students won excellence awards in Hong Kong dance competitions.
