Everyone, my name is Lee Dei Chien, this is my friend Doug. Today we'll be showing how to apply the cross-stroke from mouth. So can you wait, don't please? So guys, do play down, okay I have, I'm going to your mouth. The principle we need to make sure, Doug have his back flat on the ground so I can apply the cross-stroke. So usually cross-stroke works when I have a low amount. So, a low amount and high amount, I like to apply cross-stroke when I have a low amount. Once I put my hooks in, right here. So right here guys, I will choose my shone side. Should place my hand inside his collar, okay? I'll place my hand inside his collar, help him to set up his chest. Now it's one of the start of the work on the other side. So I push him, make a grip on his collar, and then I make an ax on my arm. So right now, as soon as I make this cross-stroke grip, I will put my forehead on the ground and drive my head to the center of his body. He's choking. So let's talk about the details right now. Okay, as soon as I put my hand inside, the first thing you will think about is going to be grab my arm right here, can't you make the bridge skate? So that's why in the same side that had my arm, I will put my hook in, charge my grip, now to make him weaker, because right now, his elbows is betraying me and him. He can't use the elbow, okay? So I will use my chest, the side of my chest on his wrist. So he look out, I will press down, and then we start opening his arm. I want his arm like this, okay? So make a grip of the collar, grab his arm, and then go sideways. My elbow has had to be in the center of his chest, just to take his weight off the head. So I go here, grab, charge my grip, he cannot go. If he hits that side of his grip, he's at that side, or the side of his grip, I will just switch my hook, so I will play with you, come back. So right now, I don't go straight here, I need to put his face on his neck. So he look out, keep my elbow on the ground, and then I will start pushing, pushing, make it his face, done inside the collar, and then go again, from put my hand inside my wrist. Cannot be like this, I had to keep my wrist straight, elbow in the center. He's a lot of weight from him, okay? He will make a grip of my hand, I give my hook in, and take his arm out. The reason I had to take his arm out is because if I try to go there, his elbow is like this, push? Yes, I have had to push my hand on the ground. So I will use my chest first, take his arm away, side open. I mean, stay here, can't make it right here, he's like, try to should leave the elbow. So here, I will keep my elbow on the ground and open. Sometimes I will put him on the ground, he can keep the head very heavy on the ground. So I will just add this variation. Put your palm facing up, drive it with full. You have more strength, make a grip on the collar. Hey, go for the pressure. All right, thank you.
