„cha qi; 茶气 - Tea nature. The inherent energetic qualities in tea. That which makes it tea. Sometimes rather unsatisfactorily interpreted as 'tea energy'; translating qi as energy suggests perhaps a rather too narrow idea of qi but it is an interesting term to consider since many people use the term.
