What are the seven-character techniques of acupuncture and moxibustion?

There are many techniques handed down from the ancients, some of which are no longer applicable, and a technique commonly used today is the seven-character technique. However, what are these techniques?
     Enter: insert a needle into a person.
     Withdrawal: The needle is withdrawn, or the skin is removed.
     Twist: Turn the needle body.
     Pounding: twitching up and down.
     Play: Fingers to play the needle handle.
     Recumbent: needle retention or oblique puncture.
     Exploring: Searching for sensations.
     Moxibustion, because it directly acts on the skin of the human body, has the effect of dredging the blood, so the effect is very good. I once treated a patient with jaundice, which was cured by taking Chinese medicine. However, he suffered from blood in the stool soon after, and taking various medicines was ineffective. Switch to moxibustion, moxibustion at Mingmen and Shenshu at the same time, a total of seven sticks of moxibustion, and one recovery. The above methods can be applied to all needle methods. Li Shouxian's "Easy Learning of Acupuncture and Moxibustion" states: "The acupoints are clear but the manipulations are unknown, and a disease cannot be treated for a lifetime." He pointed out the importance of manipulations.
