I don't quite understand the three positioning methods of Shu Fei point in Shenjiu Jinglun. Please help me explain, thanks a lot.

Hello, the first thing that needs to be clarified is that the topic should be Shen Jiujing.

The following is only based on the original text, and we don't comment on whether the original text is correct.

The first type: just below Fengmen point, under the third vertebra, with a side opening of 2 inches.

The second type: the doctor faces the patient and puts his hand on the other person's shoulder, about at the palm of the shoulder well area. At this time, the middle finger corresponds to Shu Fei. Because it is face to face, so from left to right, from right to left. This is a simple method for the famous acupuncturist in the Tang Dynasty, which is earlier than Fang's relevant records.

The third type: originally from Sun Simiao's Qian Jin Fang, "Shu Fei leads the rope to the chest", which can be understood as being flat with the chest, and winding the rope around the body for a week can get back acupuncture points.

Generally speaking, the selection of acupoints is mostly based on the content of acupuncture. For example, Shu Fei said that "the lower side of the third vertebra is one inch and five points apart." It is relatively difficult to pick points on the back, and novices really need to practice repeatedly to be proficient. The landlord looked at it so carefully that he might as well sigh. Come on!
