Features: This book is a Song Dynasty miscellany. Shen Kuo of Qiantang (1031–1095), a famous naturalist, politician, and graduate of the Jiayou Examination, compiled it in his later years while residing in Runzhou. He built Luoxi Garden and recorded his life's observations in Notes from Luoxi. The book comprises thirty volumes. It includes Record of Talks (26 volumes), divided into 27 categories such as anecdotes, debates, music theory, mathematics, human affairs, government, strategy, literature, calligraphy and painting, crafts, utensils, marvels, strange events, errors, satire, difficulties, and music discussions; Supplementary Record of Talks (3 volumes), covering only eleven of these categories; and Continuation of Record of Talks (1 volume), which is not categorized. The entire work contains 609 entries, covering topics such as astronomy, mathematics, physics, chemistry, biology, geology, geography, meteorology, medicine, engineering, literature, history, music, and art. The natural science sections summarize the achievements of ancient Chinese, particularly Song Dynasty, natural sciences. The book records important technological historical materials, such as Bi Sheng's movable-type printing, Yu Hao's Treatise on Woodworking and its architectural accomplishments, Gao Chao's advanced methods for joining rivers and sealing dams, as well as techniques for smelting iron. Shen Kuo correctly explained the imaging principle of concave mirrors, the origin of moonlight, the resonance of sound waves, and the erosional effects of water on the Taihang and Yandang Mountains. In mathematics, he summarized the summation method for second-order arithmetic progressions, known as "Xi Ji Sutras," and the approximate formula for calculating arc lengths, called "Hui Yuan Sutras." The book also describes ancient paleontology, groundwater, petrified wood, petroleum applications, and the properties of medicinal substances. Regarding historical phenomena, it provides detailed accounts of the deeds of the peasant leader Li Shun, the actual implementation of tax and labor reforms, the strengths and weaknesses of Song Dynasty's northwest and northern military strategies, and the evolution of ceremonial and ritual systems.
The earliest extant edition of this book dates back to the Southern Song Dynasty's Gandao Year 2. Currently, only Yuan and Ming Dynasty reprints of the Gandao edition remain. The widely circulated Baihai series first published the continuation of three editions. The earliest preserved version is the Yuan Dynasty edition published by the Chaling Dongshan Academy. For this publication, the original annotations were omitted, while the text was meticulously proofread based on the Qing Dynasty Guangxu Year 32 (1906) edition of Wei's Ailu in Panyu, with reference to other versions.
