There are many factors that cause this situation, but fundamentally speaking, the achievement method is not authentic, incomplete and incomplete. And because of various historical factors, most of the training teachers on the market are incomplete. At that time, what Master Qiao publicly taught was just hanging and beating, and pulp washing was a three-order nine-method twelve-method, instead of emphasizing the small, medium and big differences between light and heavy. It was invented by people who didn't know the technology, and it was never said that it would pass the customs when it was made public. Please keep your eyes open. I don't think it belongs to Buddhism, so it doesn't make sense logically.
If you are concerned about washing pulp, he emphasizes passing the exam and charging by weight. I advise you not to believe it. The swing of the body and the swing of the weight are only the first step of the authentic three-order nine-method of pulp washing, and the high-order hanging is Tian Danqi.
