Dacha Tea and Naoyuan Tea:Evidence of Close Exchanges Between Chinese and Korean Tea Cultures
Dacha tea and Naoyuan tea were the main types of tea used by the royal families of Wuyue(907-978)in China and Goryeo(918-1392)in Korea.Wuyue State used these two kinds of tea as tributes to the Central Plains Dynasties,and Goryeo used them as gifts to ministers,monks,soldiers and civilians.These two kinds of tea were produced and used throughout the existence period of Wuyue,and in Goryeo for more than 60 years from the late 10thCentury to the mid 11th Century.Dacha tea and Naoyuan tea did not appear in Goryeo until 12 years after the fall of the Wuyue,so it can be inferred that there was a close relationship between the two.As for the origin of Dacha tea,there is a record of Muzhou,but the specific location is unknown.While the origin of Naoyuan tea cannot be known without records.The unit measurement of Dacha tea mainly was"jin"and"long",which can be presumed to be loose tea.Naoyuan tea mainly used"jin"and"jiao"to measure,which can be presumed to be compressed tea.Da tea and Naoyuan tea are concrete evidence of the close inheritance and exchange of tea culture between China and Korea,which is of great significance for understanding of East Asian tea culture.
