PLEASE HELP!!!! Dying for years to know movie name

My cousin who passed away and i use to watch kung fu theatre every saturday morning as kids and although we like many of them, 1 really stuck with us and we could never figure out the name of it. Was a long time ago so forgive the description but was about a young man being trained by a master and there was a statue that the master used to teach the pressure points. The student would drop a marble or ball into the idol/statue and then have to hit the pressure points and catch the ball before it hit the ground.
Sadly that's all i have but would love to watch it again in my cousins honor and memory.
If anyone knows the name of this movie from the pitiful description I've given, please let me know by emailing me Wobalizer1@aol.com, please put kung fu movie in the description so i don't delete it thinking it's junk email. Thanks so much for any help.
