Liú Zhì 劉智 (fl. late third / early fourth century), zì Zǐfáng 子房, native of Píng-yuán Gāo-táng 平原高唐 (in modern Shāndōng), Western- and early-Eastern-Jìn court ritualist. His biography stands in Jìn shū 75 (列傳 45) — appended to that of his elder brother Liú Sòng 劉頌, the leading Yǒng-jiā-era legal scholar. He held the offices of sǎnqí chángshì 散騎常侍 and Yùshǐ-zhōng-chéng 御史中丞 in the Western-Jìn court under Sīmǎ Yī and Sīmǎ Yán, surviving the Yǒngjiā disaster into the early Eastern Jìn.
He was a Sānlǐ ritualist of the first rank, and is the named interlocutor of 虞喜 Yú Xǐ in the KR1d0094 Tōngyí fragment-record (where his Shìyí 釋疑 supplies the first ruling and Yú Xǐ’s Tōngyí the complementary judgement). He also participated in the Tàikāng 太康 1 (280) court debate on the KR1d0093 Hòuyǎng yì case of Wáng Bǐ 王毖, with his opinion given as: “lǐ wéi cháng-shì zhì, bú wèi fēi cháng shè yě” (ritual is established for ordinary cases, not legislated for exceptional ones) — proposing a one-year qī mourning rather than the full three-year period.
His birth and death years are not given in Jìn shū; documented in the Tàikāng (280–289) and Yuán-kāng (291–299) reigns, he is conventionally placed c. 245–305. The dates are left blank as no firm year is in the source. No CBDB id assigned in current dump.
