After consulting Dokbaba, Sun Zhenren explained the fifth needling method by needling thirteen ghost points. So using a fire needle three times and seven times means inserting it many times with a burning and shining fire needle.

Original: Pulse application of five needles is a ghost road, and the fire needle is fired three times and seven times. The sixth is to find an inch of ghost pillow on Dazhui.

The fifth point is called Ghost Road, that is, Shenmai Point (located in the depression just below the lateral malleolus of the foot), which is repeatedly inserted with a shiny burning needle. The sixth point is the ghost pillow, namely Fengfu point, which is located above Dazhui point, at the nape and above the hairline 1 inch.
