Miao is now shown following through on the forehand from the previous photograph. Notice how the weight has now shifted from her right leg to her left leg, and in an upwards direction as well since her legs have straightened during the stroke.
The saluting motion used by many players on the forehand side is clearly evident here, as is the synching of the free arm with the playing arm to help maintain balance. Notice also that Miao has finished fairly upright, but with a very slight forward lean, rather than a backward lean of the body, which will help her to keep balanced as well.
