Southern-Sòng Zhèngyī 正一 Daoist priest, holder of the Zhèngyī ritual title Tàishàng sānwǔ dūgōng zhílù dìzǐ 太上三五都功職籙弟子 (“Disciple of the Most-High Sānwǔ Dūgōng Office-Register”). Known only from his commentary Tàishàng dòngxuán língbǎo wúliàng dùrén shàngpǐn jīngfǎ 太上洞玄靈寶無量度人上品經法 (DZ 94), a five-juan Southern-Sòng commentary on the Dùrén jīng within the Tiāntāi-Língbǎodàfǎ 天台靈寶大法 ritual tradition. His division of the Dùrén jīng into forty-seven paragraphs matches the liturgical division of DZ 1221 Shàngqīng língbǎo dàfǎ, confirming his affiliation with the Tiāntāi version of that lineage. No CBDB record exists, and no other work is attributed to him.
