Máo Rìxīn 毛日新 of Sānqú 三衢 (modern Qúzhōu 衢州, Zhèjiāng) was a Southern-Sòng Daoist disciple of the otherwise unknown alchemical master 宋先生 Sòng xiānshēng. He is the compiler of the Liǎomíng piān 了明篇 KR5a0284 (DZ 272), to which he prefixed an autograph preface dated Qiándào 乾道 4, shíyuè shuò (1 October 1168). According to the preface, Máo “happened to meet” Master Sòng “amid the clouds” — i.e. in some hermitage — and there received from him the alchemical kǒujué 口訣 (oral formula) and a body of poems matching (“和” hé) the thirty juéjù of [[KR5a0283|Tàixuán Lǎngrán zǐ jìndào shī]] of 劉希岳 Liú Xīyuè (988). Máo edited the materials together as the Liǎomíng piān and had them printed for circulation. Nothing further is recorded of him.
