Qiulong (simplified Chinese: 虬龙; traditional Chinese: 虯龍; pinyin: qíulóng; Wade–Giles: ch'iu-lung; lit. "curling dragon") or qiu was a Chinese dragon that is contradictorily defined as "horned dragon" and "hornless dragon".
This Chinese dragon name can be pronounced qiu or jiu and written 虯 or 虬.
The variant Chinese characters for the qiu or jiu dragon are and , which combine the "insect radical" with phonetics of jiu "connect" and yin "hidden". This 虫 radical is typically used in Chinese characters for insects, worms, reptiles, and dragons (e.g., shen 蜃, jiao 蛟, and hong 虹). Compare the word jiu or "twist; entangle; unite" that is written with the "silk radical" and the same alternate phonetics as qiu 虯 or 虬.
Qiu 虬 or 虯 is also an uncommon Chinese surname. For example, Qiuranke Zhuan 虯髯客傳 "The Legend of the Curly-whiskered Guest" is a story by the Tang Dynasty writer Du Guangting 杜光庭 (850-933 CE), and Qiu Zhong 虬仲 was the courtesy name of the Qing Dynasty painter Li Fangying.
