What are the symptoms of TCM? What is the relationship between them?

Witness and state can be analogized by mathematical state space equation, which is a matrix equation of vital signs (parameters) and values; Waiting and stepping can be compared to the process in automation, that is, the development stage of metabolic process represented by a syndrome. Just as health is normal, that is, the iteration of each equation changes within a given orbit and allowable deviation, then it is constant, otherwise it is abnormal or morbid with high probability. Traditional Chinese medicine has four basic equations: yin and yang, exterior and interior, cold and heat, and excess and deficiency. According to the habits of various sects, we observe the current value of the object (that is, the matrix of syndrome and syndrome), fill in this basic equation, calculate this equation group, and get several indexes of it, such as rank and determinant. According to different sects, some follow Lingshu and Suwen, so different sects mean that this transformation (mapping) is different, some are acupuncture (a set of acupoints and techniques), some are soup (a set of prescriptions (materia medica, measurement), some are massage (a set of movements (parts, postures and techniques)), and some are wishes (a set of spells, movements and techniques).
