Huqiu Chajing zhubu 虎丘茶經注補 is a book on tea written during the early Qing period by Chen Jian 陳鑑 (1594-1676), courtesy name Ziming 子明, from the province of Guangdong. It is known that he moved to Suzhou 蘇州, Jiangsu, in 1655 and also wrote the books Caogu shiliu guan 操觚十六觀, and Jiangnan yuxian pin 江南魚鮮品.
The structure of his book on tea imitates that of Lu Yu's 陸羽 (733-804) classic Chajing 茶經 and also picks information from Lu Yu's book concerning the tea from Huqiu 虎丘 hill close to Suzhou. Chen added to these original sources from the Tang period 唐 (618-907) additional facts from his own time. In the late Ming period 明 (1368-1644), the tea from Huqiu was famous throughout China. Apart from the relevance of the tea from Suzhou, Chen's book also adds to the study of Lu Yu's Chajing because the few statements of Huqiu tea were often neglected by researchers up to then.
The text is found in the series Tanji congshu 檀几叢書.
