Guo Pu's detailed introduction.

Guo Pu (276-324), a native of wenxi county, Hedong, was the son of Guo Yuan, the magistrate of Jianping in the Western Jin Dynasty. A famous scholar in the Eastern Jin Dynasty was not only a litterateur and an exegetist, but also a master of Taoism and mathematics, and the founder of youxian poetry. At the end of the Western Jin Dynasty, the war was about to start. Guo Pu fled Jiangnan and joined the army in Xuancheng and Danyang successively. During the Jin and Yuan Dynasties, Guo Pu was promoted to Zuo Langzhong, moved to Shang Shulang, and served as a clerk of General Wang Dun to join the army. In 324, Wang Dun, who was stationed in Jingzhou, was killed at the age of 49. Afterwards, Guo Pu was posthumously awarded as "the prefect of Hongnong". Jin Mingdi built the Guo Pu Monument named "Guo Gongdun" by Xuanwu Lake. Guo Pu's son Dunau was appointed magistrate. Guo Pu once annotated Zhouyi, Shan Hai Jing, Mu Zhuan, Chu Ci and Chu Ci. Today, feng shui masters can find Guo Pu's annotations everywhere in Ci Hai or Ci Yuan. Guo Pu's representative works are Fourteen Poems about Immortals and Fu Jiang. Although his works mostly involve Hyunri, his ci works are colorful and his realm has been expanded. ? Wing Huai is different from metaphysical poems at that time. The Classic Annals of Sui Shu consists of seventeen volumes, and the collection of Guo Hongnong was compiled by Ming Dynasty. Guo Pu spent 18 years researching and annotating Er Ya, explaining the names of ancient animals and plants with the popular dialect names at that time, and making annotations and drawings for them, making Er Ya an important reference book for studying materia medica in past dynasties. The pictorial classification of animals and plants initiated by Guo Pu has also been used by all large-scale herbal works since the Tang Dynasty. From the academic origin, Guo Pu not only inherited the Yi-ology from his family, but also inherited the art and mathematics theory of Taoism. He was the most famous alchemist in the Jin Dynasty. It is said that he was good at many strange alchemies.
