Chén Xìngdìng 陳性定 (hào Shǎowēi 少微), Yuán-period Daoist of the Yùxūgōng 玉虛宫 on Mt. Xiāndū / Jìnyún 仙都/縉雲 in Chùzhōu 處州 (modern Lìshuǐ 麗水, Zhèjiāng). His sole transmitted work is the Xiāndū zhì 仙都志 KR5b0307 (DZ 602), compiled in two juǎn and prefaced in the fifth month of Zhìzhèng 8 (1348) under Yuán Shùndì. Chén styles himself Yùxū zhùshān Shǎowēi 玉虛住山少微 (“Shǎowēi, resident of Yùxū[gong]”) in the work’s table of compilers. The cult-site he served was the canonical twenty-ninth of the thirty-six Daoist grotto-heavens (the Xuándū qíxiān dòngtiān 玄都祈仙洞天) and the legendary place of Huángdì’s 黃帝 ascent on the huǒlóng 火龍.
