He paused for a moment and said, "A full pulse indicates heat syndrome, but if it's weak and thin upon long pressing, how could it still be heat syndrome? Therefore, according to the comprehensive analysis of pulse and symptoms, the patient's condition should be characterized by the clear yang being unable to rise and the turbid yin being unable to descend. The cold below is real; the heat above is false."
By this time, Wu Buwei had finished reading Du Heng's record of the patient's symptoms and said with sudden understanding, "Clear yang unable to rise, life fire weak, thus unable to warm the body, so the patient feels cold and their limbs are cold. Fire unable to generate earth, so the spleen cannot function properly, hence the poor appetite and diarrhea.
In this case, all yin cannot be coordinated by yang qi, so dizziness and vomiting occur in the upper body, while frequent and uncontrollable urination occurs in the lower body."
