Most of her best work was done in the late 1970's and early 80's - in basic kung fu films - but her career stretched into the 90's when she appeared in a few classic Girls with Guns films - Princess Madam and Angel Terminators.
Her first film - Kung Fu Master Named Drunk Cat - was made in 1978 and she followed this with a number of other kung fu films. At that time she was called Lady Jackie Chan. Unfortunately many of these early films are not all that easy to find.
These are some films that contain some of the
best Yeung Pan Pan roles (some I have seen, others not).
