Form 27 (Dan Bian) Xia Shi(Lowering Movement-Single Whip)

The form is so named because the lowering movement of the body is like a hovering eagle drops suddenly to rush  at a rabbit. Names for Xia Shi (lowering  movement) vary in different routines  when it is supported by different hand  techniques. The 42 Forms include two Xia Shi postures, Dan Bian Xia Shi (Single Whip and Lowering Movement) and Chuan Zhang Xia Shi (Thread Palm and Lowering Movement). Dan Bian Xia Shi consists of two connected movements, namely Xia Shi and Dan Bian (Single Whip).

Detailed Explanation
Lower limbs: Curve the left leg to a full squat, and straighten the right leg to a right Pu Bu (crouch stance). Pu Bu is one of the basic stances in Chinese martiat arts, formed by parting two legs left and right 4 t0 5 times the length of foot, with one leg bent to a full squat while the knee and tiptoes pointing outward, and the other leg straightened close to the ground, both feet landing on the ground completely. When the left leg is straightened, it is called Zuo Pu Bu (left crouch stance), and when the right leg is straightened, it is called You Pu Bu (right crouch stance).
Upper limbs: Raise the left hand in a hook shape to the left shoulder height; swing the right hand over the face to the inside of the left elbow, and thread it forward before the abdomen along the inside of the right leg, eyes looking at the right palm.

Key Point
Keep the body straight and centered, with the bent leg landing on the ground compietely without lifting the heel.The leg for lowering movement should be straightened.
