Michuan shuilong jing 秘傳水龍經

Michuan shuilong jing 秘傳水龍經, brief Shuilongjing 水龍經, is a book on geomancy written during the Ming period 明 (1368-1644) by an unknown author. Text and images were compiled by the geomancer Jiang Pingjie 蔣平階 (1616-1714), courtesy name Dahong 大鴻, from Huating 華亭 in Songjiang 松江, Jiangsu. Jiang wrote quite a few book and manuals on geomancy, like Dili bianzheng 地理辨正, Zizijin 字字金, Tianyuan yiyu 天元餘義, Yangzhai zhinan 陽宅指南 or Xiangdi zhimi 相地指迷.

The Shuilongjing interprets the shape of flowing waters in the context of geomancy. The idea behind the book is to search for the presence of "dragon lairs" (longxue 龍穴) in the presence of creeks and rivers. The book consists of a huge number of images of various shapes of creeks. It is introduced by a detailed preface written by Jiang Pingjie, the original preface, and a general introduction (Zonglun 總論).

The text is included in the series Jieyue Shanfang huichao 借月山房彙鈔, Zhihai 指海 and Zeguzhai chongchao 澤古齋重鈔.
