Lǐ Xuéyù 李學裕, Kāngxī-period pupil of 胡煦 Hú Xù (1655–1736). Took the manuscript of Hú’s monumental 99-juàn Zhōuyì hán shū away for editing but died before completion; the manuscript was thereby scattered and lost. The surviving 18-juàn Zhōuyì hán shū yuē cún (KR1a0145) was reconstructed by Hú’s son 胡季堂 Hú Jìtáng from extracted essential material.
