It is also said that there are many taboos in the application of Thirteen Ghost Points. First of all, the date of birth, acupuncturist, accounts for at least two Yin Shi; The second is to attract ghosts with silver needles; The third is persuasion. Do not stick 13 stitches, 6 ~ 7 stitches at most. Just drive away the monsters and don't kill them all, or the doctor will ask for trouble. Acupuncture doctors should use it with caution.
