《黄帝内经·灵枢·终始》
脉象坚实有力的，治疗时，就应当用深刺的方法去针刺，出针后也不要立即按闭针孔，以使邪气尽量外泄。脉象虚弱无力的，治疗时，就应当用浅刺的方法去针刺，以调养脉气，使之不过于损耗，出针后还应急速地按闭针孔，不使邪气再行侵入。
重舌，刺舌柱以铍针也。手屈而不伸者，其病在筋；伸而不屈者，其病在骨，在骨守骨，在筋守筋。补须一方实，深取之，稀按其痏，以极出其邪气。一方虚，浅刺之，以养其脉，疾按其痏，无使邪气得入。
For a pulse that is solid and strong, during treatment, you should use a deep stabbing method to acupuncture, and do not press the acupuncture point immediately after removing the needle, so that the evil qi can be released to the maximum extent possible. For a pulse that is weak and powerless, during treatment, you should use a shallow stabbing method to acupuncture, in order to adjust the pulse qi and prevent it from becoming too deficient; after removing the needle, you should also press the acupoint quickly to prevent the evil qi from invading again.
