Kung Fu Pigtail Lady

[Ash]

Trying to remember the name of a movie I saw years ago back in the 80's.  It was a kung fu film and this little 60 year old lady knew how to fight and had six short pigtails.  Three on the left side of her head and three on the right.
In one scene she grabs a guys face, puts it up to her head and whips him from left to right with the pigtails.  As in most kung fu movies, it makes a ridiculously loud smacking noise when they hit.

I watched it with my stepbrother and we were laughing our a**es off when we watched that scene.

Anyone know what movie it is?
