Analysis of Doubts in the Artificers' Record (Unknown) - Page 16

...durability. Without refined precision original: "wei zhi" (微至). This refers to the minute accuracy of the wheel's construction or its point of contact with the ground., there is no way to achieve swift rotation original: "qi su" (戚速). A technical term in the Kao Gong Ji describing the smooth and rapid movement of a well-made wheel..

"Joining" refers to the components being attached without any gaps between them. Generally, crude craftsmanship must rely on glue and lacquer coatings to fill in spaces. However, if the components are already seamless while still in their raw state original: "pu" (樸). The unfinished or basic wooden form before final treatment., the structure is solid.

Regarding the terms "smooth retreat" and "refined precision": Masters Guang Li Guangdi (1642–1718), a Qing dynasty scholar and author of the Analysis (Xi Yi) being read here. and Zheng Zheng Xuan (127–200 AD), the Han dynasty scholar whose commentaries are foundational to understanding the Rites of Zhou. believed these meant that the portion of the wheel touching the ground is minimal. This seems unsettled. If the wheels used for mountain travel are uniform original: "mou" (侔). Meaning balanced or equal in size and weight., how could the area touching the ground be "small"? It likely refers to the fineness of the craftsmanship itself. If the craftsmanship is fine, then the rotation will be swift.

The Wheelwrights original: "Lunren" (輪人). The specific class of artisans in the royal workshops responsible for the design and assembly of chariot wheels.

Cutting the Three Materials Must Be Done at the Proper Time This refers to the seasonal harvesting of timber to ensure the wood is seasoned and durable.

Li Guangdi says: "Regarding the 'three materials,' it is not recorded which specific species of wood are meant, but they are the woods suitable for the hub, spokes, and felloe." The hub (gu) is the center, the spokes (fu) connect the center to the rim, and the felloe (ya) is the outer circular rim of the wheel.
