Changsha County is located southeast of Dongting Lake, with Yuzhang County to the east and Guiyang County to the south.

At first, after Sun Jian failed to raise an army against Dong Zhuo, he was appointed by the imperial court as the Taishou of Changsha and lived here for a period of time. Later, Liu Biao felt that Sun Jian's father and son threatened his rule in Jingzhou, so he sent Cai Mao and Huang Zu to lead a large army to attack Sun Jian from both land and water. After Liu Biao recaptured Changsha, he had no intention of continuing to the east, so he appointed his own practitioner Han Xuan as the Taishou of Changsha.

Han Xuan is the elder brother of the famous Han Hao, in the romance of a certain Luo, this person is a dog official who is jealous of his ability, impatient and likes to kill, but the actual situation is diametrically opposite. Han Xuan exterminated the Liukou mountain bandits in Changsha, organized the people to protect themselves, and loved the people like a son in peacetime, and was deeply supported by the local people in Changsha. In the official history, after Liu Bei's defeat in Xinye, he retreated all the way to the south, and when he reached Nanjun, he was blocked by Zhou Yu, and Zhuge Liang built Liu Bei to go to Changsha, Guiyang, Wuling and Lingling to develop. At that time, these four counties were located in the southern part of Jingzhou, and the military threat was small, so there were not many regular troops in the territory. Liu Biao did not appoint an heir before he died of illness, and Liu Bei came from an incorrect way, so he encountered strong resistance from the Taishou Han Xuan organization when he captured Changsha.

Liu Bei's subordinate Guan Yu attacked Changsha for a long time, so he threatened to slaughter the people in Changsha City after the city was broken to vent his anger, and Huang Zhong, the Changsha guard at that time, wanted to defect to Liu Bei, so he did not contribute to the work, Han Xuan had to kill himself in desperation in order not to implicate the people of Changsha.

In the time and space of Liu He's rise, the three peach brothers are still staying in the Luyang area to develop, and they are afraid that they will not have the opportunity to cross the river to the south for a while. Cao Cao is now making every effort to deal with Liu He north of the Yellow River, and as long as his brain is not muddy, he will not send troops to attack Liu Bei. In this way, Changsha Taishou Han Xuan does not have to kill himself.

When Jia Xu defected to Liu He, he reminded him to be on guard against the Hu people in the northern grasslands from infecting the plague and other evil diseases, and Liu He was very attentive to it. Not only did he immediately send someone to invite Hua Tuo to Yecheng to discuss countermeasures, but he also asked Tian Chou to activate the network deployed by the Military Intelligence Department in the south to inquire if a person named Zhang Ji had recently written a medical book on how to treat typhoid fever and other diseases.

After Tian Chou sent people to pass the mission to the south, Wei Yan, who had already voted for Liu Biaojun, took over the task of finding and inquiring about Zhang Ji together with several other secret piles.

After Wei Yan was received by Tian Chou in Danshui, he quietly returned to his hometown Pingchun, where he stayed for several months, and then took advantage of Huang Zu's army from Jiangxia to fight against Yuan Shu, he joined the army and became the personal soldier of Huang Zu's son Huang Shu. Wei Yan was brave and resourceful, and received more than a year of training and training in Fengxiang City. It's easy to stand out from a crowd of ordinary soldiers. It only took Wei Yan half a year to be promoted from Huang Jie's personal soldier to the position of deputy leader of the guard, that is, to become a military marquis.

After receiving the news from Tian Chou from a secret channel, Wei Yan asked Huang Jie for leave, saying that he had heard some news about his mother and wanted to leave for a while to look for his lost mother. There has been no fighting in Jingzhou recently, and Huang Jie is resting in the Xiling area in Jiangxia. He agreed to Wei Yan's leave, and gave Wei Yan a sum of money for the journey, asking him to hurry up and go back quickly.

After Wei Yan left the western neighborhood, he went straight to Changsha County according to Tian Chou's prompts. Along the road, I secretly paid attention to the news about Zhang Ji.

Liu He's Zhang Ji, the word Zhongjing, may not be very famous at this time, but he is known as a medical saint in later generations. In the medical field, only the medicine king Sun Simiao and the divine doctor Hua Tuo and others can be compared.

Zhang Zhongjing was born into a declining bureaucratic family in Nanyang, Jingzhou, and his father, Zhang Zonghan, was an official in the imperial court. Because his family was still well-off, he was exposed to many classics since he was a child. Zhang Zhongjing saw the story of Bian Que's visit to Qi Huan Gong from the history books. He developed a sense of admiration for Bian Que, which had a deep impact on his later abandonment of official duties and medical practice.

Zhang Zhongjing saw the darkness of politics and the corruption of the government when he was a teenager, when peasant uprisings broke out one after another, military disasters continued, and there were wars everywhere, and the common people suffered from the disasters of war, coupled with epidemics, many people died unexpectedly, and it was unbearable to see. However, the government and the yamen did not want to find a way to save them, but they were blindly fighting for power, waging wars, and oppressing the people. This made Zhang Zhongjing disgusted with officialdom since he was a child, despised his career, pitied the people, and germinated the desire to study medicine to save the people. When Zhang Zhongjing was ten years old, he studied under Zhang Bozu, a famous doctor in the same county, and learned medical skills.

Zhang Bozu was a well-known physician at that time, he had a calm personality, lived a simple life, studied medicine diligently, and every time he saw a patient and prescribed a prescription, he was very careful and thoughtful. Nine times out of ten, the patients he treated were cured, and he was highly respected by the local people. Zhang Zhongjing was very attentive when he studied medicine with him, whether it was going out to diagnose a patient, copying prescriptions and catching medicines, or going up the mountain to collect medicines and going home to concoct them, he was never afraid of hardship or tiredness. Zhang Bozu liked this student very much, and passed on to him the rich experience he had accumulated in his lifelong practice of medicine.

He Hao, a fellow villager who was older than Zhang Zhongjing, knew him quite well, and once said such a sentence: "Jun is not high in rhyme, and he will be a good doctor in the future." It means that Zhang Zhongjing is talented, studious, smart and steady, but he does not have the temperament and demeanor of being an official, so he is not suitable to be an official. As long as you concentrate on studying medicine, you will definitely become a famous doctor in the future.

He Hao's words further strengthened Zhang Zhongjing's confidence in studying medicine, and from then on, he studied more hard, read medical books, and extensively absorbed the experience of various doctors for clinical diagnosis, and made great progress, and soon became a famous doctor, so that "the blue is better than the blue", surpassing his teacher Zhang Bozu.

Zhang Zhongjing once carefully studied ancient medical books such as "Su Wen", "Lingshu", "Difficult Scripture", "Yin and Yang Treatise", "Placental Medicine Record", among which "Su Wen" had the greatest influence on him. "Su Wen" said: "Those who are sick with fever are all typhoid fever and the like." He also said, "If a person is wounded by cold, he is sick with fever." Zhang Zhongjing developed this theory based on his own practice, and he believed that typhoid fever is the general name of a qiē fever, that is, a qiē disease caused by external sensations, which can be called "typhoid fever". He also conscientiously studied the principle of "dialectical treatment of syndromes" left by his predecessors, and thus put forward a new insight on "the six classics on typhoid fever."

In addition to "diligent pursuit of ancient teachings", Zhang Zhongjing also "learned from all sides", extensively collected effective prescriptions for ancient and modern treatments, and even tried his best to collect folk prescriptions. He studied and accumulated extensive information on a variety of specific treatment methods such as acupuncture, moxibustion, warm ironing, medicine, medicine, bathing, moisturizing, foot soaking, ear irrigation, ear blowing, sublingual medicine, and artificial respiration. After decades of struggle. Zhang Zhongjing collected a large amount of information, including his personal experience in clinical practice, and wrote the sixteen volumes of "Treatise on Typhoid Fever and Miscellaneous Diseases".

Although Zhang Zhongjing hated officialdom and despised official career since he was a child, because his father had been an official in the imperial court, he attached great importance to his son getting an official and a half-job, so he forced Zhang Zhongjing to raise filial piety when he was Emperor Ling, so he entered the officialdom. During the Jian'an period, Zhang Zhongjing was sent by the imperial court to Changsha as a taishou. At that time, officials could not enter private houses casually. Approaching the people. But if he didn't contact the people, Zhang Zhongjing couldn't treat them, and his medical skills couldn't grow, so Zhang Zhongjing thought of a way, and chose the first and fifteenth days of the first month of the month, open the yamen widely, and let the sick people come in, and he sat in the lobby upright. One by one, they diagnosed the people with diseases.

Zhang Zhongjing also asked the officials to post a notice to reassure the people and inform the people of the news. His actions caused a strong shock in the local area, and the people all applauded and supported Zhang Zhongjing even more. It's been a long time. Zhang Zhongjing sat in the hall and formed a routine. On the first and fifteenth days of the Lunar New Year, people from all walks of life seeking medical treatment gathered in front of his yamen, and some even came from afar with luggage. Later, people called the doctor who sat in the pharmacy to treat people as "sitting doctors". It is used to commemorate Zhang Zhongjing.

Zhang Zhongjing saw that the people trusted him very much, and he kept improving his medical skills and constantly exploring. He collected a large number of folk prescriptions. Do careful research. Sometimes they are even afraid of long distances to learn from teachers. Once he heard that there was a famous doctor nicknamed "Wang Shenxian" in Tongjitang in Xiangyang City, who was very experienced in treating choke sores. He immediately took his luggage and traveled hundreds of miles to worship the "Wang Shenxian" as his teacher. He has studied and studied the uniqueness of "Wang Shenxian" in all aspects of medicinal properties and medical Taoism, and has benefited greatly.

Although Zhang Zhongjing's medical skills are very superb, there are some diseases that he cannot treat. As the saying goes, "After the GI, there will be a year of calamity." At the end of the Eastern Han Dynasty, wars were frequent, and constant wars led to plague epidemics. During the Jian'an period, the plague epidemic reached as many as 5 times, killing many people, and some towns became empty cities, especially the most people died of typhoid fever. For example, Zhang Zhongjing's family, which originally numbered more than 200 people, has died in less than 10 years since the first year of Jian'an, and seven-tenths of them died of typhoid fever.

At that time, because of the raging epidemic, some quacks took advantage of the fire to rob and did not give the patient a serious pulse diagnosis, "not enough to measure the inch, not to shake hands to the foot", and after a moment of relative illness to the patient, they prescribed medicine and grabbed medicine, only knowing how to make money. More people, although they learned from famous doctors, do not want to forge ahead, stick to the old ways, do not carefully study medical prescriptions and medical skills, in order to relieve the people's pain, but compete to chase power and glory, forgetting their own duties. Zhang Zhongjing was very angry at the practices of these quacks, rebuked them bitterly, and made up his mind to control the epidemic of plague and cure typhoid fever on his own.

Since then, he has been "diligent in seeking ancient precepts and absorbing all prescriptions", assiduously studying ancient medical books such as "Suwen", "Lingshu", "Eighty-one Difficulties", "Yin and Yang Treatise", "Placental Medicine Record", inheriting the basic theories of classical medical books such as "Neijing", extensively drawing on the treatment methods of other doctors, combined with personal clinical diagnosis experience, researching the treatment of typhoid fever and miscellaneous diseases, and began to write "Treatise on Typhoid Fever and Miscellaneous Diseases" in the tenth year of Jian'an.

During the period when Zhang Zhongjing was quietly writing "Treatise on Typhoid Fever and Miscellaneous Diseases", the warlords were fighting and the dynasty was torn apart, so Zhang Zhongjing went to Lingnan to live in seclusion, concentrate on studying medicine, and writing medical books. In the fifteenth year of Jian'an, he finally wrote an epoch-making clinical medical masterpiece "Treatise on Typhoid Fever and Miscellaneous Diseases", a total of 16 volumes. "Treatise on Typhoid Fever and Miscellaneous Diseases" systematically summarized the theory of "syndrome differentiation and treatment", and made important contributions to the development of the etiology theory and prescription theory of traditional Chinese medicine in China. Later, the book was regarded as the "ancestor of Fangshu", and Zhang Zhongjing was also known as the "Master of Jingfang".

Now Zhang Ji, has not served as Changsha Taishou, but has been famous in Jingnan, Wei Yan inquired all the way to Linxiang, the seat of Changsha County, and found that Zhang Ji was serving as the commander of Linxiang County at this time, and also posted a notice outside the county office, every first and fifteenth day of the new year, the yamen does not handle official business, only receives people with illness to come for consultation. When Wei Yan heard this, he could be completely sure that this Zhang Ji was the person Ye Cheng was looking for.

Tian Chou's instructions to Wei Yan were to find an opportunity to get close to Zhang Ji and find out if Zhang Ji had recently written medical books on typhoid fever and miscellaneous diseases, and if Zhang Ji had already started to write, Wei Yan would find a way to stay by Zhang Ji's side, protect Zhang Ji's safety, and secretly pass on the content of Zhang Ji's writings to the north on a regular basis; If Zhang Ji had not yet begun to write, Wei Yan would have to find a way to encourage Zhang Ji to leave Jingzhou and travel to the north, preferably to meet Hua Tuo.

Wei Yan's current status is not prominent enough, and the support he can get secretly is still limited, and with his status as a small military marquis, it is not easy to complete the tasks assigned by Tian Chou. However, for Wei Yan, the more difficult the task, the more he can show his skills, and there is an element of challenge and adventure hidden in his character, even if he has now embarked on a completely different path.
