The work aims to sort out the evolution of Leisi design, explore the modeling principles and evolutionary factors of traditional Leisi design, and summarize the creation ideas and design wisdom of traditional farming tools, so as to provide conceptual reference for the innovative design of agricultural machinery and equipment. Through literature analysis, comparative research and other methods, combined with historical relics and existing objects and other illustrative materials, and based on the evolution process of Leisi, a detailed analysis on the origin of shapes, evolution of materials and structure, and changes in usage methods of Leisi was carried out. The evolution of traditional Leisi can be roughly divided into three stages:pointed stick, Leisi, and plow. With the effect of factors such as mechanical principles, ergonomics, and functional characteristics, it reflects the traditional farming tool creation ideas and design wisdom of being suitable and labor-saving, efficiency first, and changing according to the situation.
