Zheng [Xuan]'s commentary to the *Liji* says: "The circumference of the outer wheel-rim is two zhang and seven chi, which is what is now called *wang* (𨊾). Its diameter is nine chi; these are all ancient regulations. The circumference of present-day wheel-rims is one zhang and eight chi, with a diameter of six chi; that is, the wheel rim." The lower character [轂] is pronounced *g[ong]* + *[w]u* [gǔ]. The *Shuowen [jiezi]* says: "Where the spokes converge." Laozi says: "Thirty spokes share one hub." It is classified under carriage (車) with *gu* (穀) abbreviated for phonetic value).
