Téng Bóxiáng 滕伯祥 (hào Lèshàn lǎorén 樂善老人), late-Sòng figure of Nányáng 南陽, the preface-author and putative transmitter of the Zǒumǎ jígān zhēnfāng 走馬急疳真方 (KR3em040). The preface, dated Déyòu yuán nián 德祐元年 (1275, the penultimate year of the Southern Sòng), reports that the author had received the manuscript from an immortal old man (lǎosǒu 老叟) encountered in 1225 at his ancestral graves, in exchange for prayers for progeny. He records that he subsequently fathered a son Guī 珪 (a zhōu sīxùn 州司訓 at Wújiāng 吳江), and lived past eighty. The preface is signed Lèshàn lǎorén Nányáng Téng Bóxiáng 樂善老人南陽滕伯祥. CBDB records one Téng Bóxiáng (id 21566, c_index_year 1214) with no further detail and no medical-authorship attestation; the cbdbId is recorded here for cross-referencing, but the identity cannot be independently controlled. The attribution is widely held to be pseudepigraphic, since the received recension contains yángméichuāng 楊梅瘡 (syphilis) material, which entered the Chinese-medical textual tradition only in the early sixteenth century — making the late-Sòng dating of the received text untenable.
