Zhāng Jiéxīn 張傑鑫 was a late Qīng professional oral storyteller (píngshū yìrén 評書藝人) in the Beijing tradition, author of the martial-arts storytelling cycle Sān Xiá Jiàn 三俠劍 (Three Chivalrous Swords; KR4k0220). No reliable biographical dates have been located; he is not recorded in CBDB. His active period was most likely in the late Qīng or early Republic of China era, roughly 1890–1930, based on the publication history of the transcribed text.
Sān Xiá Jiàn was one of the most popular storytelling cycles in the Beijing píngshū tradition. The transcribed text is of enormous length (Part 1 alone runs to 184,323 lines in the Kanripo edition), reflecting the expansive episodic structure of the oral performance genre. The narrative is set in the Qianlong period of the Qīng dynasty and centers on the chivalric exploits of three sword-heroes against a backdrop of military campaigns, secret societies, and imperial politics. Zhang’s storytelling tradition was carried on by later performers in the Beijing píngshū circuit.
