"Jiaozhou Ji" records that its horn is over three feet long and shaped like the handle of a horse whip. "Yili · Xiangshe Li" mentions that high officials used the sìzhong (a vessel for counting tallies) to obtain game according to their rank. Note: Sì is the name of an animal. "Zhou Li · Dongguan Kaogong Ji" states that sì armor is connected in six parts. Also recorded, sì armor can be preserved for two hundred years. "Yunhui" quotes Lu Dián saying: The sì is skilled at butting with its horn, so the former kings created the sìgong (a type of ritual wine vessel made from a rhinoceros horn) as a warning during drinking. "Book of Odes (Shijing) · Zhou Nan" says: Let us temporarily fill the wine cup made from the sì horn. Commentary: Sìgong is a drinking vessel made from a horn. Verification: "Zhou Li · Dongguan Kaogong Ji" states that sì armor is in six sections. Note: Sì armor lasts for two hundred years. Remark: The following sentence is also part of the main text of "Kaogong Ji," not a note. The word "Note" has been cautiously changed to "Also."
