Commentary states: Zhang Zhongjing said that in cases of hanging death, if the area below the heart remains slightly warm, life can still be saved even after a day. Ge Shi (Ge Hong) stated that if the area below the heart is still slightly warm, life can be saved even after a long time. The theories of these two schools imply that rescue is possible only if there is residual warmth (vital breath), indicating that Yin and Yang have not completely severed and the root Qi is still preserved. Otherwise, even if death has not occurred for long, survival is impossible. Generally, hanging causes a sudden and complete obstruction of the ascending, descending, exiting, and entering Qi mechanisms. If the rope is untied with proper technique, there is indeed a principle for revival; however, if the method is flawed, despite the body retaining some warmth, harm will inevitably occur, akin to "pulling the feet when saving someone from hanging" (i.e., improper intervention exacerbates the injury). Both Zhang Zhongjing and Ge Shi provided specific syndrome differentiation and rope-untie methods, which should be carefully examined.

In cases of hanging, if one perceives that death has just occurred, the victim should be slowly lowered. Although the Yin and Yang meridians may be suddenly congested and blocked, the True Qi of the Zang-Fu organs may not yet be entirely exhausted, thus allowing for potential treatment. However, if the rope is abruptly cut while the person is still suspended, rescue becomes impossible. This is because when Qi is already congested and the rope is suddenly severed, the Qi, though momentarily unblocked, scatters violently and cannot return, leading to immediate death. It is also stated that if hanging occurs from morning until evening, survival is likely even if the body has cooled; whereas if it occurs from evening until morning, treatment is difficult. This is because Yang Qi is abundant during the day, facilitating Qi flow, while Yin Qi dominates at night, hindering Qi circulation. Additionally, it is noted that summer nights are short and hot, making revival easier. Furthermore, even if Qi has ceased but the area below the heart remains slightly warm, survival is possible for more than a day. Generally, due to shorter nights and higher temperatures in summer, treatment should theoretically be feasible. For those with slight warmth below the heart, even after more than a day, rescue is possible, provided the rope is untied slowly rather than cut. The victim should be gently laid flat on bedding. One rescuer stands on the victim's shoulders, gently pulling the hair with constant, moderate tension without releasing; another presses on the chest and moves it slightly; a third massages and extends the arms and legs. If the body is stiff, gradually force flexion while pressing the abdomen. After approximately the time it takes to cook a meal, Qi may exit through the mouth, breathing resumes, and eyes open. Continuous traction and pressure should be maintained without letting go, avoiding excessive exertion. A small amount of Guixin Tang (Cinnamon Heart Decoction) and thin rice gruel should be given via the mouth, moistening the throat initially, and gradually allowing swallowing before stopping. Additionally, two rescuers should blow air into both ears using tubes, which is considered optimal and highly effective for ensuring survival.
