Xu chajing 續茶經

Xu chajing 續茶經 "Continued Classic of Tea" is a book on tea written during the Qing period 清 (1644-1911) by Lu Tingcan 陸廷燦 (c. 1700), courtesy name Zhizhao 秩昭, style Manting 幔亭. He hailed from Jiading 嘉定 near Shanghai and was district magistrate (zhixian 知縣) of Chong'an 崇安 and expectant ministerial secretary (houbu zhushi 候補主事). Except for his book on tea, he has written the "brush-notes"-style essay (biji 筆記) collections Nancun suibi 南村隨筆 and Yijuzhi 藝菊志.

His book on tea, with a length of 3 juan, was written as a kind of supplement to Lu Yu's 陸羽 (733–804) famous book Chajing 茶經 from the Tang period 唐 (618-907). Yet since Lu Yu's times, the variations of tea and preparation methods had changed drastically. In the district of Chong'an, for instance, the famous tea of the Wuyi Mountains 武夷山 (in England known as Bohea Tea) was very popular among Chinese and foreigners. During the Tang period, that region was not yet a centre of tea cultivation. The chapters of the Xu chajing are, at least in the first part, roughly the same as in Lu Yu's Chajing. The last fascicle consists of an appendix, in which the history of preparation methods is described.

The Xu chajing was first printed in 1735 by the Shouchun Hall 壽椿堂, the author's study. It is included in the series Siku quanshu 四庫全書. The editors of the series have deleted the words "Chajing" from all the chapter titles of Lu Tingcan's book to identify it as an independent work. However, this contradicts the author's idea of presenting his work as a supplement to Lu Yu's old book.

Another book titled Xu chajing and with a length of 20 juan was written by Pan Siqi 潘思齊, courtesy name Xisan 希三, from Hangzhou 杭州, Zhejiang. It is mentioned in the local gazetteer Hangzhou fu zhi 杭州府志, but seems to be lost.
