The white grape variety originates from China. The name means dragon's eye; synonyms are Czhi-Pu-Tao, Dragon's Eye, Hun-Juan-Sin, Long Yan, Lon Ye, Long Yan, Lounian, Lungyen, Lun Yan, Lungyen, Oeil de Dragon and Ryugan. It was long regarded as identical to the Japanese variety Ryugan. However, the morphological descriptions are different. The variety was a crossing partner in the new varieties Xiongyuebai and Zeyu. The late-maturing, high-yielding vine is resistant to frost. It produces greenish-yellow, full-bodied white wines with fruity flavours that are suitable for sparkling wine and brandy production. The variety is used for pressing and table grape. It is widespread in the eastern provinces of Hebei, Shandong and Shanxi. In 2016, 1,000 hectares of vineyards were designated (Kym Anderson).
