Correct stroking of your hand in forehand

Kylle Saga Asked 11 years ago

My friend always told me that my forehand stroking is wrong. He said that I had to swipe my hand in upper left direction. I'm very sure what he said is right because I usually see table tennis players swipe there hand in upper left direction!! So how do I do this kind of stroke because it's very hard to control and very hard to do!!:) can U help?
