In close combat, the key point of hugging is to grasp the inner circumference as much as possible, that is, when hugging each other, try to put your arms under each other's armpits and cling to each other's body, which makes it easier to fall or contain each other. It is the same to hold each other's neck with both hands, and the arms should be in each other's arms. Then you can hit each other's bodies with your knees.

If you want to fall, the trick is to dive suddenly, put your hands on your head, put your arms around each other's legs, and put them together hard, so it is easy to fall (if the vertical projection of the center of gravity falls outside the support surface of your feet, you will fall), and then ride up and slam.
