The little crows are chirping. When the crows disperse, only the jade screen stands empty and lonely. Suddenly the wind started blowing, and the autumn breeze blew. I felt fresh and cool beside my pillow, as if someone was fanning me with a silk fan beside the bed. While sleeping, I vaguely heard the rustling autumn wind outside, but when I woke up and looked for it, I couldn't find anything. I saw only sycamore leaves covering the steps, bathed in the bright moonlight.

1 "The Beginning of Autumn"

Era: Song Dynasty Author: Liu Han

The crows sing and disperse across the jade screen, one pillow is fresh and the other is cool wind.

There is no place to look for the autumn colors when I wake up. The steps are full of sycamores and the moon shines brightly.

2 Character brief introduction

Liu Han (medical scientist in the Northern Song Dynasty, year of birth and death unknown), a native of Linjin, Cangzhou (now Ningjin, Shandong), was a famous doctor in the Five Dynasties and Northern Song Dynasty.

Liu Han was born in a family of Chinese medicine practitioners and once served as an inspector of the National Guard Army. Later, he presented medical books and was appointed by Zhou Shizong as Hanlin Medical Officer and Chief Registrar of Weiwei Temple. After the death of the Zhou Dynasty and the rise of the Song Dynasty, Liu Han's status was further improved. He successively served as the official of Chaosan, the Prime Minister of Honglu Temple, Shangyao Fengyu, Yuanwailang of the Ministry of Industry and Commerce of the School, Medical Officer of the Imperial Academy, and Doctor of the Household Department of the School. Presided over the compilation of "Kaibao Materia Medica". Later, he was demoted to the deputy envoy of Hezhou regiment training because he misdiagnosed Liu Yu, the guard general of Huazhou. He came back a few years later and resumed his duties as Shangyao Fengyu and Hanlin Medical Officer.

He later died of illness at home at the age of seventy-two.

3 Influence of the work

The compilers of "Kaibao Materia Medica" successfully formulated a rigorous style, which was inherited by other official materia medica works in the Song Dynasty. First of all, it was the first time that black and white characters were used instead of red and ink to divide the book. The content of the herbal book "Shen Nong's Materia Medica" before "Kaibao Materia Medica" was copied with red pen; "Compendium of Materia Medica" was changed into "Shen Nong's Materia Medica" with white characters (Yin script), and other characters in black characters (Yang script), which are clear and eye-catching. Secondly, use different abbreviations to indicate the source of the text: for example, "Tangfu" means new medicines in "Newly Revised Materia Medica", "Jinfu" means new medicines in "Kaibao Materia Medica", and "Tao Yinju" means "Compendium of Materia Medica". "The annotation of "Tang Ben Cao" is the annotation of "New Materia Medica". The compilers of "Kaibao Materia Medica" used the title "Jin'an" for the annotations based on the literature, and the "Jin'an" for the annotations based on the knowledge of medicines at that time. This system of regulations has made a significant contribution to the preservation of ancient herbal literature.
