What is the difference between hunan beef and kung pao?

They are very similar, and of course recipes vary. But, Hunan has more ginger and Kung Pao has more garlic. Also, I think Kung Pao has more chiles, because it has always seemed hotter to me, than Hunan. But they are both a soy, sesame, vinegar and sugar base-so they really are similar. Also, sauces aside, Kung Pao generally has vegetables in it, whereas Hunan typically does not.
