Gejing 鴿經 is the only book on doves from the treasure of traditional literature. The book was written during the late Ming period 明 (1368-1644) by Zhang Wanzhong 張萬鐘 (1590-1644), courtesy name Kouzhi 扣之, from Zouping 鄒平, Shandong. Zhang was born into a family of high reputation and was prefectural judge (tuiguan 推官) of Zhejiang 鎮江, Jiangsu, under the Southern Ming 南明 (1644-1661). He is therefore seen as one of the Ming loyalists.
Inspite of its brevity, the Gejing is much detailed on many aspects of pigeon breeding which shows that Zhang did not just read a lot about the topic, but was also a pigeon keeper himself. The book consists of six parts, beginning with a general discussion (Lun ge 論鴿), and then proceeding to classification (Huase 花色), traditional races and types (Feifang 飛放), movements and fights (Fantao 翻跳), old sources (Diangu 典故), and literature (Fushi 賦詩). The discussion speaks about the character of pigeons, races, feather colours and other physical aspects, fly movements, sounds, housing, perches, breeding, diet, and medical aspects.
