Gù Xiànchéng 顧憲成 (1550–1612), zì Shūshí 叔時, hào Jīngyáng 涇陽, posthumous shì Duānwén 端文, of Wúxī 無錫 (Jiāngsū). Took the jìnshì in Wànlì 8 (1580); office reached Lìbù lángzhōng; xuējí (struck-from-the-register) returned home. Re-raised as Nánjīng Guānglù sī shǎoqīng but did not assume office. At the start of Chóngzhēn, posthumously Lìbù shìláng. He is the founding figure of the Dōnglín (Eastern Forest) movement: in 1604 with his brother Gù Yǔnchéng KR4e0224 and Gāo Pānlóng 高攀龍, he restored the Dōnglín shūyuàn at Wúxī, which became the centre of late-Wàn-lì factional politics and the namesake of the Dōnglín dǎng. The Sìkù tíyào preserves his collection Jīnggāo cánggǎo KR4e0223 while using it to launch the famous critical verdict on the movement: gōng Dōnglín zhě duō xiǎorén, ér Dōnglín bùbì jiē jūnzǐ (“those who attack Dōnglín are mostly petty-people, but Dōnglín are not necessarily all gentlemen”).
