Zhōu Zhǔn 周準 (hào Bàozhēn zǐ 抱真子), a Daoist / lay-Daoist of Jīnjiāng 錦江, Shàngráo 上饒 district, Jiāngxī, is known only through his preface to Dòngyáng zǐ’s 洞陽子 Jiùkǔ miàojīng zhùjiě KR5b0083 (DZ 399). According to the preface, he met Mr. Lǚ (Dòngyáng zǐ) during his travels in the Wǔyí shān 武夷山 and around Xīhú, at which time the two became sworn friends of “misty-vine” (yānluó 煙蘿) — a Daoist-reclusive bond. Zhōu’s period of activity is therefore the same as Dòngyáng zǐ’s: Sòng or Yuán. No CBDB record.
