Shuanghuai suichao 雙槐歲鈔

Shuanghuai suichao 雙槐歲鈔 "Chronicle notes from Double-Sophora [Studio]" is a "brush-notes"-style collection (biji 筆記) authored by Huang Yu 黃瑜 (1426-1497), courtesy name Tingmei 廷美. He was a native of Xiangshan 香山 (present-day Zhongshan 中山 in Guangdong) during the Ming period 明 (1368-1644). Huang served as district magistrate of Changle 長樂. He personally planted two sophora or locust trees (huai 槐) and built a pavilion between them, where he would chant and compose poetry, calling himself the "Old Man of the Twin Locusts" (Shuanghuai Laoren 雙槐老人).

In bibliographical classifications, the book of 10 juan is listed under the "miscellaneous histories" category (zashi lei 雜史類) in the bibliographical chapter of the official dynastic history Mingshi 明史, under "alternative histories" (bieshi lei 別史類) in the Qianqingtang shumu 千頃堂書目, and under the "fiction writers" category (xiaoshuojia lei 小說家類) in the the book chapter of the Qinding Xu wenxian tongkao 欽定續文獻通考 and the Siku quanshu zongmu tiyao 四庫全書總目提要.

The book documents events from the founding of the Ming dynasty up to the Chenghua reign-era 成化 (1465-1487), comprising a total of 220 entries. Huang Yuji 黃虞稷 (1629-1691), Huang Yu's grandson, discovered old documents in a book chest. He therefore added two entries to the work, thereby completing it. Alongside numerous unofficial historical anecdotes about Ming figures, the book also features stories of immortals, the supernatural, and retribution, many of which are unrelated to classical sources and are included indiscriminately. These fictional elements clearly exhibit literary characteristics.

The work exists in several editions, including a Ming-period print from the Jiajing reign-period 嘉靖 (1522-1566), the edition in the series Lingnan yishu 嶺南遺書, Congshu jicheng chubian 叢書集成初編 and Xu shuofu 續說郛.
