Doctor Jiang Yangqing holds the point of view that more than half of the chronic diarrhea cases were caused by the hypoactivity of Yang deficiency. The patients with cold type of chronic diarrhea were identified from the following aspects including texture of stool, constitution of patients, duration of diarrhea and diet-induced factors. For differentiation of chronic diarrhea due to cold syndrome, the distinction between hypoactivity of spleen yang and deficiency of kidney yang shall be distinguished clearly.
