Shen Yun is an author about whom public information is limited in Chinese bibliographic sources; two works by this author are currently held in the collection. The first, The End of the Zheng Regime in Taiwan, is a historical work that draws on the fortunes of the Zheng family in Taiwan during the late Ming and early Qing, tracing the rise and fall of that regime for readers interested in the historical context. The second, Expanded Bamboo-Branch Songs of Shanghai, falls under literary appreciation: it follows the traditional zhuzhici form, using verse to record local customs, street life, and everyday scenes in Shanghai, in plain language with a strong local flavor. One work concerns history, the other local life; though their subjects differ, both show a concern for concrete historical and local experience, with a style inclined toward plain record and description rather than elaboration. As birth and death dates, place of origin, and personal history cannot be confirmed, no inferences are made here; the account is limited to the orientation and readability of the works at hand.
