Her screen name, Cynthia Khan, was a combination of the names of established Hong Kong stars Cynthia Rothrock and Michelle Yeoh (who was then known as Michelle Khan). Expanding on Cynthia Khan's "connection" to Rothrock and Yeoh/Khan, Cynthia Khan's breakthrough came when she was cast in In The Line of Duty III, replacing Yeoh who had not only starred in In the Line of Duty II (aka Royal Warriors), but also co-starred in the first of the In the Line of Duty films (aka Yes, Madam!) with Cynthia Rothrock. Thus, one might argue that Cynthia Khan replaced both Cynthia Rothrock and Michelle Yeoh/Khan in the In the Line of Duty series.
