Ge Hong was born in Jurong County, Danyang (now Jurong County, Jiangsu). Born in the fourth year of Taikang in the Jin Dynasty (AD 283), he died in the first year of Xingning in the Eastern Jin Dynasty (AD 363). In his later years, he lived in seclusion in Luofu Mountain, Guangdong Province, where he collected herbs and wrote books until his death. In the Ming Dynasty, Chen Jiamo quoted a poem from "Praise of Famous Doctors in Past Dynasties" in the Compendium of Materia Medica to sum up his life: "Being trapped in the Louvre, you can swim and guide it, and the world is called a fairy, and your elbow can pass." 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 and medicinal chemistry, and also has many outstanding opinions in literature. His works, about 530 volumes. However, most of them have been scattered, and the main ones that have been passed down to this day are Bao Puzi and the elbow. Bao Puzi is a comprehensive work, which is divided into 20 volumes and 50 volumes. The inner chapter is about fairy prescriptions, ghost changes, health preservation, evil treatment and other things, belonging to Taoist works. But some of them, such as Then, Fairy Medicine and Huangbai, are masterpieces summarizing China's ancient alchemy. Foreign articles talk about people's gains and losses, the quality of the world and so on. Among them, Shi Jun, Shang Bo and Ci Fu are famous literary works. The prescription of saving the pawn after elbow, referred to as "elbow after elbow", is a simple and useful prescription compiled by him in Guangdong. Most of the prescriptions collected are effective, easy to collect and cheap. Moreover, the article is not big, so it can be hung behind the elbow (today's pocket edition) and can be used for first aid at any time, even in mountain villages and on trips where doctors and medicines are few. Therefore, all generations have been welcomed by the broad masses. According to historical records, Ge Hong's medical works include Synopsis of the Golden Chamber 100, Fairy Food Prescription 10, Fairy Food Prescription 4 and Jade Letter Decoction 5.
