Bai Yuxue went to the "Cuizhu Mountain" with He Zihan and Lin Pinghe with curiosity, and the beautiful scenery on the mountain made Bai Yuxue very excited, she had never seen such a beautiful natural scenery before.

Cuizhu Mountain is lined with peaks, layers of mountains, steep cliffs, on the slopes, strange stones of different sizes give people a magical reverie.

The "Funeral Valley" in the depths of Cuizhu Mountain is very hidden and full of mystery, the two sides of the valley are steep rock walls, and there is a trickle of water passing through the valley bottom, and the clear flowing water is under the shade of pine, cypress and green bamboo, which is particularly agile and full of vitality.

Bai Yuxue is relaxed and happy by the natural scenery around her, this rare natural landscape, she feels fascinated, facing the rocks, green trees, streams, springs and lovely grass, Bai Yuxue very real experience the original charm of nature.

At this time, Bai Yuxue imagined that if she could sit on the rocks by the stream, sit on the bank of the stream, watch the spring flow, and play the guqin, it would be a particularly beautiful realm.

He Zihan looked at Bai Yuxue's beautiful expression admiring the scenery of the valley, and she felt that the young girl in front of her was not only very intelligent and aura, but also quite artistic, and if the "Burial Valley" could attract more young women like Bai Yuxue, it would be very vigorous and energetic.

Lin Pinghe's wine gradually subsided, he looked at the two young women in front of him, he felt that at this time, in the "Funeral Valley", it was no longer as cold and lonely as before, and with the addition of Bai Yuxue, the valley was more interesting.

Lin Pinghe thought: "Miss Yuxue is now relying on a fanatical pursuit of an ideal state and worship of Zi Han's niece to enter the 'Funeral Valley', and she still doesn't know what Zi Han is pursuing. If she knew that Zi Han was leading the old man to develop poison, she might be very disgusted, and at that time, it would be difficult to say whether she would stay in the valley, so Yu Xue must be made to understand that the old man and Zi Han were developing poison, not to harm people, but to save people. Save more good people. Seemingly. In the past few days, the old man must tell Miss Yuxue the story about Zihan, the poisoning of my master and the murder of the Virtuous Immortal Gu, so that Miss Yuxue can understand. The development of poison is also a righteous act. ”

In fact. He Zihan also had a similar question to Lin Pinghe in his heart. It's just that He Zihan didn't tell Bai Yuxue a lot of truth, but began to teach her various skills.

He Zihan and Bai Yuxue are often together. Now, He Zihan began to teach Bai Yuxue medical skills and medical theory, and He Zihan talked about pharmacology, medical classics, and various knowledge such as looking, smelling, asking, and cutting to diagnose diseases.

He Zihan told Bai Yuxue: "The premise of the 'four diagnoses' in ancient Langzhong is to regard the human body as an organic whole, and believe that the lesions of each part of the body will affect the whole body, and the changes in the internal factors of the body will appear on the surface of the body, for example, the lesions of the internal organs will be reflected in all aspects of the body surface such as the five senses and limbs, so it is necessary to see, smell, ask, and cut. A very important principle of medical technology is to regard the human body as an organic whole, and to treat a living organism is to treat a living body, not to process the parts of an instrument, and the human body is alive, complete, and interconnected. ”

Although Bai Yuxue felt that what He Zihan said was a little abstract and obscure, she vaguely felt that He Zihan was very reasonable.

"There are two very profound views in ancient medicine, one is to diagnose and treat the human body as a living organism, and the other is to distinguish and treat human diseases. In the view of physicians, the human body is an organic whole, organs, tissues, and organs are closely interrelated physiologically, and all parts of the body maintain a coordinated and balanced state, only in this way can the body be healthy. There are two conditions for the need for good health, on the one hand, the viscera tissues should play their active and effective functions normally, and on the other hand, the viscera tissues should complement each other, balance and coordinate, so that the whole body is in a good state of balance. He Zihan said.

Bai Yuxue asked: "It seems that in the human body, there is a complex small world, all parts and tissues must cooperate well, and it is necessary to maintain a good physiological balance in order to maintain a healthy body, for example, you can't eat too much, and you can't be too hungry, otherwise, the body will be unbalanced, and people will feel uncomfortable, right, Sister He?"

Of course, the human body is not only a complex small world, but also a small world with a good management mechanism, all parts of the human body are centered on the five organs, and the five organs are organically connected with the meridian system of the whole body, constituting a whole body connected, the surface and the inside are connected, up and down, and the parts are coordinated and mutually aid in an orderly and unified whole. The rise and fall of yin and yang are related, through the changes in the physical signs of the appearance, it can be seen that the lesions of the internal organs, illness is not only a certain part of the body lesions, but also the internal balance of the body is destroyed, yin and yang are not coordinated, therefore, the treatment of diseases of course to the local lesions of the body is treated, but it is important to treat the imbalance of yin and yang as a whole, headache to heal, foot pain to heal the feet, but to treat headache, foot pain, can not stay on the head and feet. He Zihan carefully explained the medical theory to Bai Yuxue.

"It seems that it is not easy to be a Langzhong, not only to know whether the patient has a headache or foot pain, but also to know that it is the imbalance of yin and yang in those aspects of the body that causes headache and foot pain, and the human body can not be 'opened' to see, relying on what you said 'four diagnoses', and it is too difficult to know what changes are happening in the human body. Bai Yuxue said.

"In fact, there are more than these conditions, the human body is a small world, and nature is a big world, ancient physicians believed that man is 'small nature', and the whole natural world is 'nature', this big and small nature is closely linked, they are constantly in interaction, interdependence and complementarity, reaction and exchange, this is what people often say 'the unity of heaven and man'. ”

"Hehe, what Sister He said is quite interesting. A 'small nature' and a 'nature', two interact, 'man' and 'heaven' are in a united whole, heaven and man interact, you were talking about the medical skills of curing diseases at first, why did you talk about such a big truth? Is there anything to do with headaches and foot pain and 'heaven'?" Bai Yuxue asked.

"When people are sick, of course, they have a close relationship with 'heaven', and this 'little nature' is an integral part of 'nature', and everyone's life is inseparable from the natural environment. It is to survive in the natural environment. Natural changes, such as seasonal climate changes, the alternation of day and night, changes in geographical conditions, etc. will have an impact on the human body. And. The human body is also constantly responding to the influence of nature, and in the process of communication between man and nature, if the response to the environment is conducive to the establishment and optimization of the internal balance of the body. The organism will actively accept and absorb the positive elements in the process of activity, and conversely, if the reaction is not conducive to the internal balance, the organism will isolate, reject and resist it, which is a kind of 'wisdom' of the organism. Moreover, once the impact of the environment on people exceeds the scope of the human body's physiological acceptance, the human body will automatically take measures to resist, and if it can't resist, the body will be damaged, pathological reactions will occur, and the internal balance of the human body will be destroyed. He Zihan said.

"Sister He, this is too complicated, Yuxue knows, when it's cold, you have to wear more clothes, and when it's hot, you have to take off thick clothes; when you have a lot of fire, you can take some medicine to reduce fire, and if you have a cold on your body, you can eat some hot food, can you think about it so complicated?" Bai Yuxue felt that He Zihan's speech was too cumbersome, and she raised doubts.

For example, it is necessary to take into account the relationship between the diseased part of the body and the internal organ system, the relationship between the diseased part of the body and the viscera, qi and blood, yin and yang, the relationship between the human body and the surrounding environment, and the previous condition of the body and the new conditions that may occur after the use of medicine, etc. 'Syndrome' is to identify pathology, to judge and summarize the pathology of the body at a certain stage in the development of the disease, so as to recognize the location, etiology, nature of the disease and the relationship between good and evil in the body, and to understand the nature of pathological changes; 'syndrome differentiation' is to understand the symptoms and signs through the 'four diagnoses', and to analyze and judge the nature of the pathology; and 'treatment' is to determine the corresponding treatment method. On the contrary, if the same disease has different symptoms, it is necessary to use different methods to treat the specific disease, the living body is very complex, the cause is also very complex, and different diseases have different symptoms because of different specific conditions, which cannot be treated with the same method, which is '' Different diseases but the same symptoms can be treated in the same way, which is 'different diseases and the same treatment', and these views are all significant manifestations of syndrome differentiation and treatment. He Zihan carefully explained the medical theory to Bai Yuxue.

"Sister He, listening to you say so much, so complicated, Yuxue's head is dizzy, and she has to 'identify', 'prove', 'discuss' and 'treat', as well as the cause, pathology, signs, symptoms, etc., your head will swell after listening to it, in fact, what you said is that you should first see the doctor carefully, and then determine what the disease is, and then think of a good way to treat it, and finally prescribe medicine for treatment?" Bai Yuxue asked.

"Haha, you are very smart, you can understand the complex medical theory and treatment methods in a simple way, this is a smart way, what you just said simply, in fact, it is the four basic steps of treatment, that is, syndrome differentiation, legislation, prescription, medication, first, through the guò 'four diagnoses' and so on to identify, find out the cause and pathological changes; secondly, according to the symptoms found in the careful diagnosis, formulate the basic principles of treatment; thirdly, according to the treatment rules to formulate or select appropriate, Finally, choose the right medicine for the symptom and use it skillfully in the prescription to start the treatment of the patient. He Zihan said.

"Sister He, what you have said now is complicated enough, and what you will talk about in the future will become more and more complicated? Yuxue's brain is about to explode, I can't stand it!" Bai Yuxue said.

"Sister Yuxue, are you starting to retreat and don't want to learn medical skills?" He Zihan asked Bai Yuxue sternly.

Bai Yuxue faced He Zihan's question, she didn't know how to answer, in fact, Bai Yuxue wanted to learn medical skills very much, but she felt that what He Zihan said was too difficult to understand and difficult to understand.

Bai Yuxue said: "My little sister wants to learn very much, but I can't digest what Sister He taught for a while, can you talk about something more interesting?" (To be continued......)
