Lushan Mountain and Gehong in Balu Town

In Balu Town, pingnan county, there is a mountain with an altitude of 204 meters, also known as Yiyang Mountain or Geyi Mountain. There is a Gexian Temple at the highest peak of the mountain. Geyi Mountain is named to commemorate Gehong's coming to Quyang Mountain to collect medicine and make an alchemy. Ge Hong, whose real name is Zhichuan, is Bao Puzi. He reads widely and carefully studies classics, history books and medical books. He is a famous Taoist theorist, physician and alchemist in China. Known as Ge Xianweng. Jurong County, Danyang (now Jurong County, Jiangsu Province). Born in the fourth year of Taikang in Jin Dynasty (AD 283), he died in the first year of Xingning in Eastern Jin Dynasty (AD 363). Ge Hong was born and died in troubled times. He lost his father at the age of thirteen and his family came down. He received alchemy and Taoism from Andrew. When Hui Di was in the Western Jin Dynasty, he was named General Fu Bo for his achievements. After abandoning armour and retiring to seclusion, it was the rebellion of eight kings and they were displaced to the central plains States. At the beginning of the Eastern Jin Dynasty, Guan Neihou was given a food intake of 200 cities. Later, he was recommended as an ordinary waiter and a great writer. If you quit, you won't I heard that there was red sand on my toes, so I asked for an order to check the leak (now Guangxi Beiliu). After arriving in Guangzhou, he was retained by Deng Yue, the secretariat, and lived in seclusion in Luofu Mountain, Guangdong Province in his later years. He was an alchemist, collecting herbs and writing until his death. In the Ming Dynasty, Chen Jiamo quoted a poem from Praise of Famous Doctors in Past Dynasties in Compendium of Materia Medica to sum up his life: he lived in seclusion in Luofu, guided by good deeds, and achieved immortality through Tao. But this only shows his side of alchemy and medicine collection and seeking immortality in seclusion. And the other side of him was ignored. In fact, he was a famous scientist in ancient times. He has made many important discoveries and creations in medicine, especially in immunology and chemistry, and also has many outstanding opinions in literature. There are about 530 volumes of his works, but most of them have been lost. The main works that have been handed down to this day are Bao Puzi, Fang Yi, synopsis of the Golden Chamber and Xijing Miscellanies.

According to the Records of Pizhou and Ancient Pizhi of Suining, in the fourth year of Jin Xiankang (AD 338), 55-year-old Ge Hong came to Yangshan in Pizhou to collect medicine and make an alchemy. According to "Tracing the Origin of Hundreds of Surnames: Ge", in the Eastern Han Dynasty, Ge Lu helped Guangwudi to make great contributions to table tennis and was named the Hou of Xiapi County. Ge Hong came to Xiapi to calculate his ancestral home. He identified Pinellia ternata produced in Pizhou as Pizhou drought and named it Pixia. Promoted the production and medicinal use of Pinellia ternata. Therefore, Yiyang Mountain got the name of Geyi Mountain. There are still the remains of Ge Hongjing and Ge Hongdong at the top of the giant mountain, which proves that Ge Hong lived on the giant mountain for a long time. According to legend, Ge Hongdong lived in Ge Hong's residence, and Ge Hongjing was used by Ge Hong to get water for alchemy. In ancient China, this famous mountain was a specialty in Fuyang, and it was visited by Ge, which added mystery. The mountain is not high, but the fairy is famous. The arrival of Ge undoubtedly added charm to Pizhou, a giant mountain. There are many dogs in the mountainous areas around Pizhou, and rabies is prevalent. The mortality rate of this disease is almost 100% so far. Ge Hong believed that there was a way to fight poison with poison in ancient times. In Huangdi Neijing, it is said that poison should be used to treat diseases, but there is no poison to treat diseases. Ge Hong thought that when a mad dog bites, it must be the poison in the dog's mouth, which invades the human body from the wound and makes people poisoned. Can the venom of mad dog be used to treat this disease? He caught and killed the mad dog, took out its brain and applied it to the wound of the rabies patient. Sure enough, some people won't get sick again. Although some people get sick, they are lighter and avoid the bad luck of death. Ge Hong has taken preventive and therapeutic measures against rabies, which can be regarded as a pioneer of immunology. Immunology in Europe began in Pasteur, France. He artificially infected rabbits with mad dog disease, and took out the brain marrow of the diseased rabbits for injection to prevent and treat mad dog disease. This principle is basically similar to Ge Hong's principle. With the support of modern science, Pasteur's immunization method is certainly more scientific, but it is later than Ge Hong's 1600 years. Ge Hong is the enlightenment and pioneer of immunology.

Like other parts of the world, smallpox, which threatens people's lives, occurs from time to time in Pizhou Giant Mountain. Ge Hong wrote in Elbow Emergency Prescription: One year, a strange epidemic occurred, and the patients were covered with blisters and sores. At first it was little red dot, and soon it became a white pustule, which was easy to break. If not treated properly, blisters will grow and fester, and people will have a high fever. Nine times out of ten, it can't be cured. Even if it is cured by luck, it will leave a small scar on the skin. The small scar began to turn black and became the same color as the skin after one year. This strange epidemic described by Ge Hong was later called smallpox. Western doctors believe that the earliest record of smallpox was the Arab doctor Rezas. In fact, Ge Hong lived more than 500 years before Reza. Ge Hong should be the first medical scientist to record smallpox.

Ge Hong called tsutsugamushi disease sand louse poison. It has been made clear that the pathogen of sand louse virus is a microorganism smaller than bacteria, called rickettsia. There is a kind of insect called sand louse, which stings people's blood and injects it into the human body, making people sick and have a fever. Sand lice grow in the south. According to the survey, tsutsugamushi disease is prevalent only in Guangdong and Fujian provinces in China, and it is extremely rare in other places. Ge Hong gained knowledge about this disease through hard practice. It turned out that he loved alchemy and lived in Luofu Mountain, Guangdong Province for a long time. There are sand lice in the mountains and grasslands near here. Sand lice are smaller than small grains of rice, so you can't find them without careful observation. Ge Hong not only discovered sand lice, but also knew that it was the vector of tsutsugamushi disease. His record is earlier than that of American doctor Pam 1500 years. Pam only recorded that it was not until the 1920s that foreign countries gradually discovered that the pathogen of tsutsugamushi disease was Rickettsia, which was much smaller than bacteria, and found out the life history of the spider with the pathogen. As early as 1600 years ago, without a microscope, Ge Hong made it clear about its pathogen, symptoms, location, route of infection, post-treatment and prevention, and pointed out that this disease was found in Lingnan, which is no different from what is seen in clinic today. This is a great thing. Although Ge Hong was obsessed with alchemy and cultivation of immortals, he found some laws of material changes in the process of alchemy and became a pioneer of modern chemistry. In the Inner Chapter of Bao Puzi, we can find that Ge Hong has done experiments on the reduction of mercury and cinnabar. In his book, he said: cinnabar becomes mercury when it burns, and becomes cinnabar after it accumulates. Cinnabar, also known as Cinnabar, is red mercuric sulfide. It decomposes into mercury (mercury) when heated. Mercury combines with sulfide to produce red mercury sulfide. This may be one of the earliest products made by chemical synthesis, and it is a great achievement of alchemy in chemistry. Ge Hong also found a variety of medicinal compounds or mineral drugs in his experiments. Up to now, what is widely used in Chinese medicine surgery is the medicine obtained by Ge Hong in chemical experiments. Ge Hong's alchemy was later spread to western Europe, which became the foundation of the development of modern pharmaceutical chemistry and the cornerstone of modern chemistry.

China ancient scientists should add Ge Hong. Pizhou, a fertile soil, provides a lot of basic information and scientific data for Ge Hong's research.
