Zhōu Yún 周雲 (Míng; dates and native place unrecorded) is the attributed author of the Shéndào dàbiān xiàngzōng huátiān wǔxīng 神道大編象宗華天五星 (KR3fa011), an eleven-juǎn compendium of stellar astrology and fēnyě 分野 doctrine. Nothing further is reliably recorded; the Sìkù tíyào notes that the attribution is conventional and that the work has the character of an enlarged late-Míng astrological encyclopaedia built up around an earlier nucleus. CBDB has six homonyms; id 42831 is the conventional match without confident disambiguation.
