Kaizhang may be called 'opening palm' in English. Both arms are opened spread eagle in a straight line, either palm up or palm down. There is the slightest arc in the straight line, to maintain a bracing power. Point of contact can anywhere along the upper body or arm, most likely on or close to the body, so the arms are extended soon in the action - the elbows are not flicked out.
