古代王公大臣以下的车制比五辂车制更复杂,这除了“上得兼下,下不得僭上”原则和“礼穷则通,下得通上”造成混乱之外,历代的官制不同也是个重要原因。先秦以前比较简单,虽有公侯伯子男五等爵之分,但实际行政性质的级别只有公、卿、大夫、士四级制:“孤乘夏篆,谓五色画毂约也。卿乘夏缦,夏缦,亦五采画,无篆。大夫乘墨车,墨车,不画,但以漆革车而已。士乘栈车,不革鞔而漆也。” In ancient times, the ministries and commissions of the ancient princes and ministers were more complicated than the five-car system, except that “the principle of” letting go under both “and” The different official systems of successive generations are also an important reason. Before the Qin Dynasty is relatively simple, although the male and the son of five sub-jazz division, but the actual level of the administrative nature of only male, Qing, doctor, Shi four-level system: “ By summer 缦, summer 缦, also five drawing, no seal. The doctor by Mexico, ink, not painting, but to paint the leather car only. Car by stack, not leather and paint also. ”
