This kung fu movie is kind of old. I remember watching it in the 80. There are these people with a marble that they show to a person with the fighting style of an element like earth fire water wind. Don't know any names but its not the elemental ninjas

Was it the Avatar cartoon series? Or Warriors of Virtue?

No but thank you I know those very well. This movie they fight then one noticed the style and presented a marble and the other fighter also showed a marble and they can control the elemnts earth wind
