The initial action of pulling flowers is to shake the wrist holding the cup from left to right, and the key point is to shake the wrist horizontally from left to right. This action only needs the strength of the wrist, not the whole arm. When shaken correctly, the cup will begin to show traces of white zigzag milk bubbles. Gradually move the cup backwards and reduce the shaking amplitude. Finally, when closing the cup, draw a thin straight line forward and draw the stem in the cup as the end.
