This refers to the topic at hand. It does not mention the Yi Spear original: "Yi Mao" (夷矛). At approximately 24 chi (nearly 5.5 meters), this was the longest spear used in chariot warfare, designed for long-range thrusts. individually because, when the height of the rear crossbar original: "Zhen" (軫). The wooden frame forming the base of the chariot carriage. is included in the calculation, it completes the "six grades" of height. Thus, it is already fully accounted for.

Whenever examining the principles of chariot construction, one desires the joinery to be solidly compact original: "Pu-zhu" (樸屬). A technical term for components being so tightly and naturally joined that they seem like a single piece. and the craftsmanship to be meticulously refined. If the parts are not solidly compact, the vehicle cannot be considered a complete or durable work...
