Zhāng Zhòngshēn 張仲深 (Yuán; the zhòngshēn is the given name, zǐyuān the zì). The Sìkù tíyào deduces the identity from the Suìjìn shī line “zhào wǒ xiāngguān mèng — xiāngsuí dào Màochéng” (Màochéng being the old name for Yínxiàn) + Nàyán 納延’s Huái Míngzhōu Zhāng Zǐyuān exchange-poem → therefore a Qìngyuánlù (Yínxiàn / Míngzhōu) man, zì Zǐyuān. Same poetic exchange-circle as Nàyán, Yáng Wéizhēn 楊維禎, Zhāng Yǔ 張雨, Wēi Sù 危素, Yuán Huá 袁華, Zhōu Huànwén 周煥文, Hán Xìng 韓性, the brothers Wū Běnliáng 烏本良 and Sīdào 斯道. The collection KR4d0535 was lost; the Sìkùguǎn reconstructed it from the Yǒnglè dàdiǎn into 6 juǎn. Mùbài with Mèi Zhòngshēn 暨仲深 (per Tiěfǔ zhōng lián shī small-note) — i.e., a homophone different person — is to be distinguished.
