Giving high importance to the water is one of the characteristics of Chinese tea culture,which is reflected in the multidimensional exploration of the"source of water",the"quality of water",the"boiling of water"and the"Daoism of water"by ancient people.Ancients were persistent in their pursuit of the"source of water".In modern society,the consumption of purified water has become widespread,and famous springs and waters serve more as a cultural landscape"network",nourishing the hearts of tea enthusiasts in a subtle manner.Unlike the contemporary scientific perspective on water,discussions about the"quality of water"in ancient times were conducted from the perspective of natural history,emphasizing the appropriate match between the origin and tea.It is characterized by categories like"alive""pure""sweet""cold"and"light".This approach also preserves the characteristics of natural history,which acknowledges the spirituality of all things.Ancient tea books extensively discuss the"boiling of water",focusing on three steps:"storing water""using fire"and"waiting for the soup".In spite of the advanced modern scientific instruments,the mastery of the"waiting for the soup"is irreplaceable,and technological means remain only as an aid.The"Daoism of water"is reflected in the relationship between man and water.Water provides the primitive metaphor for ancient Chinese philosophers,and Chinese Daoism enriches water with profound meanings.The mutual influence between man and water illustrates the Chinese wisdom of the unity between heaven and humanity.
