 Now, for the third exercise, get into the same position and then we're going to do tu tsao, which means stripping hand. So, go like this and then two things are happening at the same time. One hand is slicing and stripping like you're stripping off a sanding piece of wood. And the other one is pulling this way. So, you have two rotating opposite rotations. And then as you go here, you're going to do the same thing on the other hand. So, see how they're rotating in opposite directions and you're slicing or you are stripping off the skin, just imagine, off the other hand.
