A hào (“pen-name”) meaning “Daoist of the Rest-Retreat” used by multiple figures in Chinese history. The [[KR5c0110|Dàodé zhēn jīng yì jiě]] (DZ 721) is attributed under this hào; Isabelle Robinet (Schipper & Verellen 2004, 2:1409–14) identifies the author as Lǐ Kàn 李衎 (fl. 1312), a Yuán-era scholar-official.
Primary identification: Lǐ Kàn 李衎 (fl. 1312, Yuán):
- Zì Zhòng bīn 仲賓.
- Posthumous name Wén jiǎn 文簡.
- Native of Jì qiū 薊丘 (northern China).
- Scholar-official of the mid-Yuán period.
- Author of Zhú pǔ xiáng lù 竹譜詳錄 (1 juàn) — a treatise on bamboo.
- Author of the [[KR5c0110|Dàodé zhēn jīng yì jiě]] (DZ 721, 4 juàn) — under the hào Xī zhāi dào rén.
Secondary possibility: Lǐ Róng 李榮 (Táng). The Yuán shǐ yì wén zhì 元史藝文志 5:41–42 also lists a Xī zhāi dào rén by this name. However, internal evidence (see KR5c0110) makes the Lǐ Kàn identification more probable for DZ 721.
Philosophical profile. The author of DZ 721 is a moderate Confucian-inclined scholar with an interest in the Dàodé jīng — not a Daoist alchemist or Chóngxuán mystic. The commentary references the Mèngzǐ 孟子 heavily and uses lǐ 理 in the Neo-Confucian sense of “ultimate truth” rather than in a specifically Daoist ontological sense.
Dating. If Lǐ Kàn: active c. 1312. No precise lifedates. No CBDB record identified.
Disambiguation. The hào Xī zhāi 息齋 was used by multiple figures across different periods. Do not conflate this Yuán-era Xī zhāi dào rén with other bearers of the same hào in Chinese literary and religious history.
