The Yulin 喻林 "Forest of metaphors" is an encyclopedia compiled by the Ming period 明 (1368-1644) scholar Xu Yuantai 徐元太. Xu Yuantai was very interested in metaphors and parables in all types of traditional literature and collected these kinds of literary illustrations over a time period of more than twenty years. The 120 juan "scrolls" long book (according to some sources, between 38 and 80 juan) is divided into 10 chapters dealing with cosmology, politics, human affairs, education, and objects of daily life. The whole book covers 158 themes for which he quoted from more than 400 different books. His citations are very diligent, indicating the name of the book, the author, and even the name and number of the chapter. Inspite of the scholarly effort he put into his compilation, there are a lot of errors in his citations, and he also changed the original text in his quotations.
There oldest print, with a length of 80 juan, was made in 1589. The Yulin in included in the collectaneum Siku quanshu 四庫全書. It has been republished in 1991 by the Shanghai guji press 上海古籍出版, a print from 1615 was reproduced in the same year by the Shanghai cishu press 上海辭書出版社.
