Zhèng Wénbǎo 鄭文寶 (953–1013), zì Zhòngxián 仲賢, of Nínghuà 寧化 (Tīngzhōu 汀州, modern Fújiàn). Son of 鄭彥華 Zhèng Yànhuá, the Zhènhǎi jiēdùshǐ 鎮海節度使 of the Southern Táng, and personal disciple of 徐鉉 Xú Xuàn. He served briefly as Jiàoshūláng 校書郎 of the Southern Táng before the dynasty’s fall in 975. Under the early Sòng he was Tàipíngxīngguó 8 (983) jìnshì, rising through frontier and supply commissions to become Shǎnxī zhuǎnyùnshǐ 陝西轉運使 (Tax Transport Commissioner of Shaanxi) and Bīngbù yuánwàiláng 兵部員外郎. He played a major role in early-Sòng campaigns on the Tǔfān 吐蕃 and XīXià 西夏 frontier and is the author of Yīnshān zálù 隂山雜錄 (a manual on northern frontier statecraft) and PòLǔzōu 破虜奏 (campaign-memorial). His best-known book today, however, is the Jiāngbiǎo Zhì 江表志 KR2i0011 in 3 juàn — the principal early-Sòng narrative of the Southern Táng written from the inside, dated to Dàzhōngxiángfú 3 / 1010 in his own preface — and the NánTáng jìnshì 南唐近事 of Tàipíngxīngguó 2 (977). His relationship with 徐鉉 — formally bowing to the banished old teacher, who accepted the bow seated — was a famous model of literati zūnshī 尊師 in Northern-Sòng intellectual culture. He was equally famous for visiting the captive 李煜 Lǐ Yù in straw raincoat and bamboo hat. CBDB id 428 confirms 953–1013, in agreement with the Sòngshǐ and Dōngdū shìlüè biographies. CBDB id 111904 is a homonymous later figure with no dates.
