-Form 71. Stretch the R elbow against the two feet and the. Lock the elbow and L knee, open R kua, lock R kua and R knee, rotate to face to the front.
-Turning flower at the bottom of the sea. Split ourselves into two. Hold/stop the posture so hard to finish but throw ourselves out(不流水), body stops, power is thrown out.
-Parting the wild horse mane is in half horse stance.
-Cross hand.is stretching against the two feet. When open, L arm is higher than R arm.
-Fist draping over body. Central axis is maintained. Arm triangle structure is locked(elbow stays bent), squeeze the shoulders into the kua to flip the arm. When, here it is very easy to stick the elbow out or move the elbow first. We have to lock the elbow in position with the hand. When this happens, I have to twist(拧) my forearm more to bring the hand to the front.
