The rotating stick is not as simple as you said. The key point is that the cane can be rotated by the cooperation of fingers or palms, which can be divided into flat palm rotating cane, finger blocking rotating cane, finger rotating cane, sliding chain rotating cane, finger clamping rotating cane and so on. You can watch the video of Funing Xiaolong or Zi Ling about the rotating stick. The explanation is very detailed and understandable. But when practicing baseball, it often falls off at first. When you first practice, nine times out of ten you can drop it. Really, you should find your own feelings and understanding after understanding the essentials. I suggest practicing the tie bar first.
