Zhōu Zǐliáng 周子良 (zì Yuánhé 元龢; 497–516), a disciple of Táo Hóngjǐng 陶弘景, native of Rǔnán 汝南郡 in Yùzhōu 豫州, who lived as a youth at Qīnghuàlǐ 清化里 in the western suburb of Jiànkāng 建康. The text [[KR5a0314|Zhōushì míngtōng jì 周氏冥通記]] (DZ 302), edited and annotated by Táo Hóngjǐng and presented to the Liáng court in early 517, is the diary of Zhōu’s visionary encounters with subterranean zhēnrén 真人 of Máoshān 茅山, kept across a sixteen-month period before his suicide. According to Táo’s preface (1.3b–4a), Zhōu was orphaned of his father and entered Táo’s service at the age of twelve (508). He received successively the xiānlíng lù 仙靈籙, the Lǎozǐ wǔqiān wén 老子五千文, the Xīyuè gōng jìn hǔbào fú 西嶽公禁虎豹符, the Wǔyuè tú 五嶽圖, and the Sānhuáng nèiwén 三皇內文. He took his own life by the elixir of the immortals at age twenty in 516; Táo recovered the diary from a Máoshān cave where Zhōu had hidden it shortly before his death, and edited it as the four-juan míngtōng jì 冥通記. Beyond Táo’s biographical preface, no further information is preserved.
