In the 1970s she was one of the leading actresses of the cinemas of Hong Kong and Taiwan, particularly known for her roles in wuxia films and her work with director King Hu.

[1][2] Feng answered a casting ad at age 15, which led to a minor role in King Hu's film Dragon Gate Inn (1967).

[3] About two years later after her small role in Dragon Gate Inn at the age of 19 she got a leading part in King Hu's classic martial arts epos A Touch of Zen (1971).

She played the daughter of general Yang, who had to flee the capital after her father was murdered by assassins of the imperial eunuch Wei.

Her performance was later described by the film critic Richard Corliss (Time) as the screen's gravest, most ravishing woman warrior.

Originally she just viewed them simply as a commercial product and means to earn living, but after traveling with King Hu to the Cannes Festival to represent A Touch of Zen, she started to regard films as an art form as well.
