What does it mean for Chen Taiji to turn around and put his hand on the lotus?

Chen taiji passed the double lotus? Double fingers are slapping your feet with both hands.

Erect; Hold one leg straight, swing your toes outward, kick the other leg obliquely with a straight hook, and then cross the front (or head). At this time, both hands beat the instep of the right foot, making a snapping sound and continuing to swing down to one side of the body, which is called swinging leg.

Two hands are called double shot and one hand is called single shot.
