Liú Bīn 劉賓 of Fùyuán 敷原, late-Southern-Sòng collator (校正) of the 1265 (Xiányán yǐchǒu) Jiǔjiāng print of 朱熹 Zhū Xī’s Yuán běn Zhōuyì běnyì (KR1a0031) commissioned by 吳革 Wú Gé. His collation mark at the end of each juan is one of the philological signs by which the Sìkù editors identified this print as the textually clean archetype of Zhū Xī’s original twelve-juan recension.
