In the history of Chinese tea, the water from Zhongling Spring is regarded as the 1st Grade for brewing tea. This famous Spring is located at the river bottom of the Yangtze River at the foot of Shidan Mountain, on the west of Jinshan Mountain in Zhenjiang City, Jiangsu Province.
It’s an ascending spring which is formed by the upwelling of groundwater along the limestone cracks. Only in the dry season, when the river is at ebb tide, the spring mouth might be exposed to the air, so it’s quite hard to get the spring water. Only at midnight or noon, people can tie the water hyacinth made of copper ball, pot body and pot lid to a rope and sink them at the center of the river. When the water hyacinth just reaches the spring cave, they will pull the rope and open the lid to obtain the true Zhongling Spring water. The water is sweet, clear, brisk, so Zhongling Spring was praised as the Greatest Spring of the World by Liu Bochu, a spring water evaluation specialist in the Tang Dynasty (618-907).
