灵枢经·背腧 The Back Transport Points
黄帝问于歧伯曰：愿闻五藏之腧，出于背者。歧伯曰：背中大腧，在杼骨之端，肺腧在三焦之间，心腧在五焦之间，膈腧在七焦之间，肝腧在九焦之间，脾腧在十一焦之间，肾腧在十四焦之间。皆挟脊相去三寸所，则欲得而验之，按其处，应在中而痛解，乃其输也。灸之则可刺之则不可。气盛则写之，虚则补之。以火补者，毋吹其火，须自灭也；以火写之，疾吹其火，传其艾，须其火灭也。
Huangdi asked Qibo, saying: 'I wish to hear about the transport points of the five viscera that emerge on the back.' Qibo said: 'The great transport point of the back is located at the tip of the Zhu bone, the first thoracic vertebra. The Lung Transport point lies between the third vertebra; the Heart Transport point lies between the fifth vertebra; the Diaphragm Transport point lies between the seventh vertebra; the Liver Transport point lies between the ninth vertebra; the Spleen Transport point lies between the eleventh vertebra; and the Kidney Transport point lies between the fourteenth vertebra. All of these lie flanking the spine, about three cun to either side. To locate and verify them, one presses upon the spot, and if this produces a response within — the pain being relieved — this is indeed the transport point. These points may be treated with moxibustion, but not with needling. When the qi is exuberant, one drains it; when it is deficient, one supplements it. When supplementing with fire, one should not blow upon the flame, but let it die out on its own. When draining with fire, one should blow briskly upon the flame, causing the moxa to burn quickly, until the fire itself burns out.'
