In cases of *Jie Xiong* (Chest Binding) due to Cold Damage, people nowadays do not distinguish whether purgatives have been used or not, and immediately call it *Jie Xiong*, administering Zhiju Tang (Bitter Orange and Fructus Trichosanthis Decoction), which sometimes results in a true *Jie Xiong*. They fail to realize that *Jie Xiong* is caused by premature purgation; if no purgative has been used, it is not *Jie Xiong*, but rather pathogenic factors from the exterior transmitted to the chest, not yet entering the fu organs. Although there is fullness and oppression, it remains at the exterior level and belongs to the Shaoyang pattern. It can be treated with Xiaochaihu Tang (Minor Bupleurum Decoction) added with Zhishi (Immature Bitter Orange) and Jiegeng (Platycodon Root) to relieve the oppression. If ineffective, combine this formula with Xiaoxianxiong Tang (Minor Intra-thoracic Knot Decoction); one dose brings immediate relief, miraculous as if by divine power. This method should be kept secret and not told to ordinary people. Only when *Jie Xiong* is formed due to premature purgation can Xiantong Tang (Knot-Loosening Decoctions) be used, treating it gradually according to depth, avoiding overly harsh methods, for this is the highest part of the clear pathways; excessive purgation will damage Yuan Qi (Primal Qi). In Taiyang disease patterns, with fever, aversion to cold, headache, and anhidrosis, this indicates Cold damaging Ying Blood (Nutritive Blood), and Mahuang Tang (Ephedra Decoction) should be taken to disperse. Doctors who do not understand may mistakenly use purgatives, severely injuring Ying Blood and resulting in Pi Man (Fullness Syndrome). In Taiyang disease patterns, with headache, aversion to cold, fever, and spontaneous sweating, this indicates Wind damaging Wei Qi (Defensive Qi), and Guizhi Tang (Cinnamon Twig Decoction) should be taken to dispel pathogens and secure the exterior. Doctors who do not understand may mistakenly use purgatives, severely injuring Wei Qi and resulting in *Jie Xiong*. Ying and Wei correspond to Yin and Yang. Confusing these with Cold/Heat or Yin/Yang patterns leads to grave errors. Treatment methods are recorded in subsequent sections.

Regarding diseases where the body is not hot, the head does not hurt, initially there is aversion to cold, cold limbs, abdominal pain, vomiting, diarrhea, curling up while lying, silence, no thirst, and a deep, slow, and weak pulse, everyone knows this must be a Yin Pattern. However, regarding fever, red face, restlessness, removing clothes and blankets, and a large pulse, people often fail to recognize them, mistaking them for Yang Patterns, erroneously administering Cold-Cooling Medicines, leading to many deaths. One must not know that for Yin Patterns, regardless of heat or no heat, medication must be based on the pulse, which is most appropriate. Regardless of whether the pulse is floating, sunken, large, or small, if it feels weak under the fingers and completely vanishes upon heavy pressure, it is Fu Yin (Hidden Yin), and cooling medicines must not be given, as administration will lead to death. Immediately administer Wuji San (Five Accumulations Powder) to resolve exterior and interior cold simultaneously, resulting in quick recovery. If there is deep-seated cold within, Shengjiang (Dried Ginger) and Fuzi (Prepared Aconite Root) must be used to warm, and absolutely avoid dispersing/sweating methods. Even if the pulse is surging and large, if it is weak upon pressing and completely vanishes upon heavy pressure, it is a Yin Pulse. Mistaking Fu Yin patterns for Heat patterns and treating them with cooling medicines will cause thirst to increase and dryness to intensify, making survival impossible. This emphasizes relying on pulse diagnosis rather than symptoms alone.
