Yongchuang xiaopin 涌幢小品

Yongchuang xiaopin 涌幢小品 "Minuscule (or: unworthy) book from the Yongchuang Studio" is a "brush notes" essay-style (biji 筆記) book from the Ming period 明 (1368-1644), with a length of 33 juan. The author is Zhu Guozhen 朱國禎 (d. 1632), courtesy name Wenning 文寧, style Pinghan 平涵, Qiu'an Jushi 虬庵居士, a high official of the Ming central government.

The book was finished in 1621 and had originally the title Xi Hong xiaopin 希洪小品, in remembrance of Hong Mai's 洪邁 (1123－1202) book Rongzhai suibi 容齋隨筆, but the text was renamed after Zhu had built his new Yongchuang Studio.

The content of the Yongchuang xiaopin is primarily political and addresses numerous contemporary political issues. Zhu Guozhen provides extensive coverage of central-government affairs, detailing not just specific cases and their resolutions but also examining the overall structure of the administration, along with anecdotes about notable figures and common practices in the Ming capital, Beijing. He also discusses issues beyond the capital, such as the problem of coastal piracy in China and peasant uprisings. As part of a private history written by an insider, the narratives in the Yongchuang xiaopin are notably reliable.

The first print was produced during the Tianqi reign-period 天啟 (1621-1627). It was republished in 1959 by the Zhonghua Shuju Press 中華書局 and is included in the series Biji xiaoshuo daguan 筆記小說大觀.
