Hóng Shuǐ
All oolongs that are not from the Dong Ding mountain, but are made in Dong Ding style and who win a place at the competition, are now referred to as 红水, Hóng Shuǐ.[1]
So while all Dong Dings are 红水 Hóng Shuǐ technically, in terms of the manufacturing process, not all 红水 Hóng Shuǐ are Dong Dings.
