Zhāng Guānguāng 張觀光 (lifedates uncertain; Sìkù internal reconstruction gives c. 1245 – after 1324), zì Zhífū 直夫, hào Píngyán 屏巖, native of Dōngyáng 東陽 (Wūzhōu / Jīnhuá, Zhèjiāng). A minor Sòng-end / early-Yuán literary figure documented through his single surviving collection Píngyán xiǎogǎo KR4d0439 in one juàn. Attached to the Hángzhōu Yuán-period poetic society around Qiú Yuǎn 仇遠 仇遠 (per the Hé Qiú Shāncūn jiǔrì yínjuǎn poem in the collection). Took first place in the Yuèzhōng poetry society’s Zhěnyì (Pillow / Yìjīng) theme. Once briefly held a junior xuéguān (Confucian school office), possibly as Guǎngwén bóshì (Erudite of Letters). His Sòng-loyalist affect (per the Wǎnchūn jíshì “cuckoo / fallen-kingdom” line) is firm; the New Year Jiǎzǐsuìdàn poem dated 1324 (Tàidìng 1) confirms his long survival into the late Yuán. CBDB person 27951 (lifedates blank).
