Wu Lu, whose biographical information is currently unavailable, is known through the representative work Food Collection (Shipin Ji), classified in the library under medicine. Based on the available evidence, the work centers on food and is closely related to traditional knowledge of dietary health, food therapy, and materia medica, a common subject in classical Chinese health-preserving literature. Taking food as its starting point, the author compiles relevant knowledge and uses, with a practical style that emphasizes the regulation of daily diet and dietary dos and don'ts rather than abstract theoretical exposition. Works of this kind were often used in the home and consulted by physicians in ancient times, and they hold some value for understanding contemporary views on diet, knowledge of food properties, and food-therapy practice. Food Collection remains the main window for understanding Wu Lu; its background, transmission, and specific contents require further verification, and readers may consult relevant research in medical history and food history.
