Zhū Chángwén (1039–1098; zì Bóyuán 伯原, hào Lèpǔ 樂圃), a native of Sūzhōu 蘇州, passed the jìnshì of the yǐ (second) class while still very young (Zhìpíng 4, 1067) but, suffering from a chronic foot ailment (zújí 足疾), declined the appointment to take office and instead retired to manage the family-owned Lèpǔ Academy 樂圃書院 in Sūzhōu, where he taught and wrote for some twenty years. On the recommendation of Sū Shì 蘇軾, he was at length appointed Sūzhōu jiàoshòu (prefectural educational officer); subsequently summoned to court as Tàicháng bóshì (Erudite of the Court of Imperial Sacrifices), promoted to Mìshūshěng zhèngzì (Editor of the Imperial Library) and Shūmìyuàn biānxiū (Compiler of the Bureau of Military Affairs), and died in office. He is the author of the Wújùn tújīng xùjì KR2k0010, the Lèpǔ yúgǎo 樂圃餘藁 (a poetry collection), the Qín shǐ 琴史 (the earliest extant systematic history of the qín lute), and the Mòchí biān 墨池編 (a collection of treatises on calligraphy).
