Qia (Nail Pressing), as explained in the *Shuowen Jiezi*, means piercing with the fingernail. The *Yupian* explains it as pressing with the fingernail. Zhou Yufan stated: Qia refers to entering via the nail. Xia Yuzhu stated: Using Qia to replace acupuncture. For children who have been ill for a long time and are critically ill, first press the Renzhong (GV26) acupoint with the nail to test their reaction. If they cry immediately or continue crying for several times, there is still hope for survival; otherwise, if the cry sounds like a crow's caw or there is no sound at all, it is difficult to treat. However, the physician should not give up easily, striving for even a slight chance of recovery, which embodies the benevolent virtue of a healer.
The operation of Qia involves using the thumbnail to press on the therapeutic acupoints, applying light or heavy pressure according to the situation.

Da Hengwen is also known as Zong Xin Jing (General Heart Meridian) and Xiao Tian Xin (Little Heavenly Heart), located at the base of the palm, serving as the source of all meridians. Pressing here with the nail activates all meridians and is effective for various diseases. If coughing is severe, additionally press the first segment of the middle finger; if there is much phlegm, additionally press one segment on the back of the hand. Since nails are considered the surplus of tendons, pressing the inner side stops vomiting, while pressing the outer side stops diarrhea. (*Anmo Jing*)
