60.309

其紖（下陳忍反廣雅紖索也鄭注禮記云紖所謂牽牲犢之係也牛曰紖馬曰韁從糸引聲也）。

Its tether (其紖: the second character is pronounced *chen* + *ren* [= *zhèn*]. The *Guangya* says: "*Zhèn* means a rope." Zheng [Xuan's] commentary on the *Liji* says: "A *zhèn* is the tether used to lead sacrificial calves." For oxen it is called *zhèn*; for horses it is called *jiāng* [rein]. It is derived from 糸 with 引 as phonetic).
