Who are the medical sage, the historical sage, the poetic ghost, the book sage, and the poetic demon?

Medical Sage: Sun Zhongjing.

A famous medical scientist in the late Eastern Han Dynasty, known as the Medical Sage. According to legend, he once promoted Xiaolian and served as the governor of Changsha, so he was called Zhang Changsha. Zhang Zhongjing collected medical prescriptions extensively and wrote the masterpiece "Treatise on Febrile and Miscellaneous Diseases" which has been handed down from generation to generation. The principle of syndrome differentiation and treatment established by it is the basic clinical principle of traditional Chinese medicine and the soul of traditional Chinese medicine. In terms of prescriptions, Treatise on Febrile Diseases and Miscellaneous Diseases also made great contributions, creating many dosage forms and recording a large number of effective prescriptions. The treatment principles of syndrome differentiation based on the six meridians established by him have been highly praised by medical scientists of all ages. This is China's first medical monograph that establishes the principles of syndrome differentiation and treatment from theory to practice. It is one of the most influential works in the history of Chinese medicine. It is an essential classic work for later scholars to study traditional Chinese medicine. It is widely valued by medical students and clinicians.

Historical Sage: Sima Qian

Sima Qian (145 BC or 135 BC~?) was a historian and writer of the Western Han Dynasty. Zi Chang, Zuo Fengyi, was born in Xiayang (now southwest of Hancheng, Shaanxi Province). He was born in the fifth year of Zhongyuan (145 BC) of Emperor Jing of the Han Dynasty. One theory is that he was born in the sixth year of Jianyuan (135 BC) of Emperor Wu of Han Dynasty. The year of his death cannot be determined. Sima Qian began to study ancient book biographies at the age of 10. Around the years of Yuanguang and Yuanshuo during Emperor Wu of the Han Dynasty, he studied "Gongyang Chunqiu" from the modern writer Dong Zhongshu, and also studied "Guwen Shangshu" from the ancient writer Kong An. When he was 20 years old, he traveled south from Chang'an, the capital, and traveled throughout the Yangtze and Huaihe River basins and the Central Plains, inspecting customs and collecting legends wherever he went. Soon he became a doctor and became the bodyguard and retinue of Emperor Wu of the Han Dynasty. He accompanied him on many western tours and was once sent as an envoy to Bashu. In the third year of Yuanfeng (108 BC), Sima Qian inherited his father Sima Tan's position and was appointed as Taishi Ling, in charge of astronomy, calendar and royal books, so he could read the books collected by historians. In the first year of Taichu (104 BC), the "Taichu Calendar" was established with Tang Du, Luoxia Hong and others to replace the "Zhuanxu Calendar" inherited from Qin. The new calendar adapted to the needs of the society at that time. After that, Sima Qian began to write "Historical Records". Later, because he defended Li Ling who surrendered to the Huns, he was convicted and sentenced to prison and castrated. After he was released from prison, he was appointed Zhongshu Ling, and continued to write books vigorously, and finally completed the "Historical Records". People call this book "Tai Shi Gong Shu". It is China's first biographical general history and has a profound influence on later historiography. "Historical Records" has vivid language and vivid images, and is also an excellent literary work. Sima Qian also wrote the "Book of Bao Ren'an", which recorded his imprisonment and torture and his ambition to write a book, which has been praised by generations.

Poetry ghost: Li He

Li He (790-816), whose courtesy name was Changji, was from Changgu (now Yiyang, Henan). He was famous for his Yuefu poems. His poems are rich in imagination, strange in conception, and have an extremely romantic style. The poem reflects the strong dissatisfaction with the eunuchs' monopoly and the separatist rule of vassal towns, and also expresses concern for the suffering of the hardworking people. But there are also some works that reveal the gloomy mood of the impermanence of life.

The sage of calligraphy: Wang Xizhi.

Wang Xizhi (303-361, 321-379), also known as Yishao, was born in Linyi, Langya (now Linyi, Shandong), and later moved to Shanyin (now Shaoxing, Zhejiang). He was promoted to General of the Right Army and Internal History of Kuaiji. In his later life, he was called King of the Right Army and King of Kuaiji. Wang Xizhi learned from Zhong Yao in regular calligraphy, Zhang Zhi in cursive calligraphy, Li Si, Cai Yong, etc., and learned from the strengths of others. His calligraphy is known as "the dragon leaps over the Tianmen, the tiger lies in the Phoenix Tower", giving people a sense of tranquility and beauty, which is in contrast to Zhong Yao's calligraphy. His calligraphy is round and solemn, easy to translate into music, and he is tired of using the pen. He completely broke through the brushwork of official script and created the beautiful and elegant modern style of calligraphy. He was revered as the "Sage of Calligraphy" by future generations. Authentic works of Wang Xizhi's works are hard to come by, and all we see are copies. Wang Xizhi's regular script, Xing script, Cao script, Fei Bai script, etc. are all available, such as "Le Yi Lun", "Huang Ting Jing" in regular script, "Seventeen Tie" in cursive script, "Aunt Tie" in running script, "Kuai Xue Shi Qing Tie", "Sang Luan Tie" wait. His regular script "Lanting Preface" is the most representative.

Poetry Demon: Bai Juyi

Bai Juyi (772-846), whose courtesy name was Letian, was also known as Xiangshan Jushi in his later years. His ancestral home is Taiyuan (now Shanxi), and later moved to Xia Denggui (now Weinan County, Shaanxi). In his early years, his family was poor and he had more exposure to and understanding of social life and people's sufferings. In the 16th year of Zhenyuan (800) of Emperor Dezong of the Tang Dynasty, he was awarded Jinshi and was awarded the title of Provincial Secretary. During the Yuanhe period of Emperor Xianzong of the Tang Dynasty, he served as Dr. Zuo Shiyi and Zuo Zanshan.

In the 10th year of Yuanhe (815), Prime Minister Wu Yuanheng was killed by people sent by Pinglu Jiedushi Li Shidao. Bai Juyi expressed an urgent request to arrest the murderer, offended the powerful, and was demoted to Jiangzhou Sima, and later moved to Zhongzhou Governor. Emperor Mu Zong of the Tang Dynasty was appointed as the governor of Hangzhou in the early years of Changqing. He actively built water conservancy projects, built embankments to prevent floods, released and diverted lake water, and irrigated thousands of acres of farmland, with outstanding achievements. In the first year of Baoli reign (825), Emperor Jingzong of the Tang Dynasty was appointed as the governor of Suzhou, and later became the minister of the Ministry of punishment.
