In the ten chapters of Cha Jing written over a thousand years ago, it covers a series of subjects ranging from tea culture, tea art, tea history, botany, biology, agriculture, medicine, geography, hydrology, pottery, tea farming machinery to tea production.

The text in Cha Jing is surprisingly sparse containing about 55 pages and just over 7000 Chinese characters. This is because Cha Jing was written in a traditional classic literary language called Wen Yan Wen, a highly condensed, refined and poetic styled written Chinese often used by scholars and poets. Unfortunately today there are not many people who fully understand or appreciate this beautiful classic literary language.

Tea in Lu's writing refers to powdered tea, an ancient tea which gave way to loose tea leaves in the 13th century. (The ancient Chinese molded steamed leaves into cakes. To make a brew, the cake was crunched into powder and then boiled.) The book may seem of little practical value to a modern reader, for almost all the listed processes are abandoned in modern green tea production, but owing to Lu's writing - tea has become an independent subject in Chinese culture ever since.
