Moon was born in Hong Kong to a mother of Shanghai descent and a father of descent. In her primary school days, Moon lived in Taiwan with her father. Then she returned to Hong Kong and attended Jing-yi Girls' Junior High School. At the age of 13, Moon developed a passion for ballet and classical Chinese dancing. During secondary school on a holiday season, Moon joined an acting training course at RTV studio which subsequently led to supporting roles and modeling. She also underwent Martial Arts training under the guidance of Tsui Siu Ming to prepare for the physical demands required in her roles. With her dance background, she was able to excel.
Moon's performance came in where she actively participated in some intense action scenes. The role pioneered the Girls with Guns sub-genre and established her status as a bona fide action heroine.
Following a string of action films, she left the entertainment industry in the late 90's and launched the Moon Dancing Studio, a dance school for children. In 2001, she married Dennis K. Law, a renowned surgeon who has now retired and has undertaken a second career in the arts production industry, and later she gave birth to their daughter. The two filed for divorce in 2007.
While performing the final stunt in Devil Hunters , Moon sustained a third degree burn. Moon was supposed to jump off a window from a second story building to evade an explosion. Due to bad timing by the pyrotechnicians, she was engulfed in flames before she jumped down, resulting in severe burns to her hands and face. The epilogue of the film includes details about the accident, along with a message of gratitude from the director.
