Cheng Dan’an introduced chokkashin shinpo 直下進針法 in 1955, and oshideshin shinpo 押手進針法 in 1957. For both methods, it involved seppi 切皮 (piercing the skin). In Japan, the method involves senpi 穿皮 (penetrating the skin). Senpi is an acupuncture technique that includes seppi.
*Seppi切皮 (piercing the skin): The moment when the needle is struck through the skin and pushed into the body by making the skin tense.
*Senpi 穿皮 (penetrating the skin): The moment when the needle is placed on the skin, wait until the skin stops resisting, and slowly inserted into the opened skin pores or the skin pulls the needle into the body. This acupuncture technique includes seppi.
**In China, the philosophy of senpi does not exist; only seppi exists.
***Senpi hardly induces pain. Generally, seppi hardly induce pain as well, however, it will likely induce pain or s shock when the diagnosis of the patient’s body condition is inappropriate for seppi 切皮 to be practiced.
1. Chokkashin shinpo 直下進針法
1) Hold the needle less than 1.5 cun with the right hand, place the needle tip on the acupuncture point, lightly massage the circumference of the point with the left thumbnail, and insert the needle. Twist the needle in one direction with the right hand upon needle insertion.
2) Hold the long needle more than 1.5 cun with the right hand, place the needle tip on the acupuncture point, support the needle tip with the left thumb and index finger, seppi the needle into the skin with power and push it in deeply.
(Dr. Seino’s note)
The fact that this acupuncture technique is the most used technique in China shows that there were many disciples of Cheng Dan’an and after his death, quite a few were associated with the education.
2. Oshideshin shinpo 押手進針法
Disinfect the acupuncture point and the practitioner’s fingers, hold the cotton with the left thumb and index finger, insert the needle tip in the cotton, place the left hand on the stimulating point, and press the skin with the other three fingers of the left hand.
(Dr. Seino’s note)
This is an imitation of the Japanese acupuncture technique. Cheng Dan’an implemented the idea of disinfection after studying in Japan. Also, he introduced Japan’s very own technique called oshide 押手 (needle supporting hand). This technique is meant to assist needle insertion without or with minimal pain. Here, it is introduced as a ‘supporting hand’ to insert the long needle, which differs from the actual use and the true meaning of the technique. Chinese needles are made from one wire and its head is made by wrapping the wire around itself, allowing it to be very strong. On top of that, the Chinese practitioners utilize a much thicker needle compared to Japanese practitioners, hence, its structure is suitable for piercing the skin. This acupuncture technique harnesses the characteristics of Chinese needles. However, this technique is difficult to practice with thin needles, thus, thick and hard stainless needles are mainly used in China.
Although Japanese needles also include thick and hard needles, they utilize the technique called oshide, the hand that is not inserting the needle. When using thin and soft needles, shinkan 針管 (guide tube) is used. An acupuncture technique that uses shinkan is called kanshinhou 管鍼法 (tube acupuncture technique). This was invented by Waichi Sugiyama, an acupuncture doctor 鍼医 (Jp. hari-i) during the Edo period. Starting in China, it is now used all over the world. Both, chokkashin shinpo 直下進針法 and oshideshin shinpo 押手進針法, are called nenshinho 捻鍼法 (twisting acupuncture technique). This has been practiced in China since ancient times and has also been passed on to the next generations in Japan. In Japan, even for thin needles, there is an acupuncture technique with nenshinho 捻鍼法 (twisting needle technique) using oshide. It can be said that this technique evolved in japan.
