A Comprehensive Reading of the Essentials of Qi Min

"Qi Min Yaoshu" is a comprehensive agricultural book compiled by Jia Sixie, an agriculturist in the Northern Wei Dynasty. It is also the earliest and most complete ancient agricultural book in China. It was written around the 6th century AD. In the title of the book, "Qi Min" refers to the common people, and "Yao Shu" refers to the important methods of making a living, which points out the practical value of the book. The book has 10 volumes in total and covers a wide range of content: from the cultivation of food crops (such as wheat, rice, and millet), vegetables, and fruit trees, to livestock and poultry breeding, aquatic product fishing, and even food processing technologies such as winemaking, sauce making, and pickles, as well as details such as crop pest control, soil improvement, and the use of agricultural tools. Jia Sixie wrote this book by collecting folk experience, consulting ancient books, and combining it with his own practice. The book emphasizes that "when the weather is favorable and the land is favorable, you will use less effort and achieve more success." It advocates following the laws of nature in agricultural production, which embodies a simple ecological outlook. This book not only summarizes the agricultural production technology during the Wei, Jin, Southern and Northern Dynasties, but also preserves a large number of ancient agricultural proverbs and production experience, which has a profound impact on the development of agriculture in later generations. It is known as the "Encyclopedia of Ancient Chinese Agriculture" and is still an important document for studying ancient agricultural history.
