Preface: The article reproduced here is by Mr. Zhang Shanlei, a famous Chinese medicine practitioner and educator of Chinese medicine in the late Qing Dynasty and the early Republic of China. Mr. Zhang (1873 – 1934), Jiangsu Jiading (now belongs to the Shanghai Municipality), endowed with intelligent, diligent and studious since childhood, read a lot of books, especially in the Park School of exegesis. Because of his mother’s illness of wind paralysis, he often took medicine and abandoned Confucianism to study medicine, specializing in the medical books of the past dynasties, and learning with the Ming doctors, who were becoming more and more precise in their medical practice. Mr. Zhang has profound attainments in various clinical disciplines as well as diagnosis and medication, and is known as “Three Zhangs and Three Da’s” in China. On the medical not to be tasted There is no limit to the way of learning; if you get a foot, you get a foot; if you get an inch, you get an inch. The art of six arts, the skill of a hundred crafts, as well as the industry of sericulture, agriculture and nursery, sound, light, chemical and electrical specialties, and the practice of one of the arts and Xu enough to stand on their own. In the get its fine, benefit things and help people, and enough to irrigate the students; trick to get its coarse, the amount of work, but also can make a living. If we must implement the common man and blame it to the summit, very different from the mediocre stream, then the physical infinite, a hundred years of suffering, there are not easy to say. This hundred academic, shallow on the deep, see the wisdom, are to listen to the scholars of their own choice, and can not be preset a frame, in order to achieve the best of them. But the medical science is not. The intricacies of pathology are infinite; the vagaries of disease are endless. Both have been research, hanging pot, will not be able to set their own program to announce to the public that: you but when I know the disease to seek treatment, and do not know the disease, I am trapped and trapped. If its half-knowledge, shallow self-analysis, rate of goblet, rash attempts, meet light evidence, and restored to the ease of use; will see a large evidence, and fearfully do not know how to handle carry on. In today’s and confident for the insight into the wall, to tomorrow’s cowardly no ink fall carry on, is bound to panic, miscellaneous drugs indiscriminately cast, non-special clinical to do the experimental field, and has been waiting for the sick body in the practice of shooting the swan. I know that when the people who are not, the people who have been injured, wailing and wailing, can not be sundown. Covering the physician’s pen, believe in waving the pen, and the patient’s life, miserable in the blade, look into the heart of the night, can not be queried? And the world also has a cover from the hiding of the poor, do not ask about the risk of disease, do not distinguish between the cold and warm flavor of the medicine, but choose a very light, very peaceful number of things, mixed together into a formula, and then to perfunctory. I say that even if you do not go to the disease, like this flavor is clear in the water, the force is as thin as a cloud, but also no reason to err on the side of human life. Poorly enough to secure the simplicity, listen to the public comment. This is a solid specialty of the time, the usual skills of the wise, not always in an invincible place and never teach people to the mouth of the capital? I know that there is no neutral reason for the disease, and if you do not go back, you will go forward, and the situation is inevitable. The patient, how do you know? How dare you hide your body, at the command of the quacks under the wrist, but it is a car salary cup of water, no help in times of danger, or to sit back and lose the opportunity to quietly watch the success or failure. Even if a hit is not hit, and more visits to the wise, but also more wasted in the front, not easy to save. The fatigue of the wrong medicine, but also with poison to kill, how to share the club edge? Not to mention that a drug has a drug of character, with not when, but also will be a disaster, the levy of books, evidence to see and hear, all can be cited. Why the Bureau of the people are always obtuse and do not know the realization, although the hijacking of luck for the, false to if people, and not in any of its responsibility, I fear that God is good to return, out of the ordinary, planting the cause of the evil, may not be a good result also. Lament since the Qin and Han have come down, such as medicine in the art of divination, the high-minded eye to a small way, thin this is not, and listen to its non-shi not the flow of business, pretexts to make a living. Road of the unquestionable, has been more than two thousand years, the study of the truth, since the two. This study will stay in the sky, Yingxian generation, what generation of no talent? Can get their own teacher, it is not far away. If its thick cultivation foundation, take the essence of macro, and more extensive with the insights, deep to experience, the temporary diagnosis, a pulse can be identified, there are tongue can be characterized to the evidence for the side references to the shape and color for the actual basis, even if it is said that the internal organs have no language, it is not difficult to know as if it were a finger on the pulse. Drinking water on the pool, and how to blind blind heart, no opinion. Contempt! When this trend of shock in the fall, peeking at my side, when patting their backs and strangling their wrists. In fact, they are in the school, but also in the childish era, and the future generation of children, coarse new knowledge of the fur, but also to revive the rhetoric, contempt for the national essence and disdain for a look forward to, only because of the habit of seeing the city on the mediocrity of the stream, more than no shortcut, but dare to denigrate its delusional wantonness, wisdom and other mountain cream, the physics of the mystery of this reasoning? Not buried in ten years can not be commented on. I hope the aspiring people to encourage.
