What grade does Lanfei belong to?

According to the query of tea drinking network, Princess Tan Xuelan belongs to high-grade tea. Tan Xue Lanfei is produced in an alpine tea garden at an altitude of 1000 meters above Mengding Mountain in Sichuan Province. Fresh leaves of high-quality alpine tea trees before the Ming Dynasty were selected and dried by shaking, scattering, grasping, pressing and tying, which promoted the formation of color, aroma, taste and shape quality of tea. Princess Lanfei has both the sweetness of Mengding Gan Lu and the refreshing orchid fragrance. The fragrance comes from the tea itself, which makes people feel relaxed and refreshed.

When this kind of tea is brewed into a cup, it feels like "a piece of new tea has a broken nose". The taste is fresh, mellow and refreshing, strong but not bitter, mellow but not light, and the aftertaste is sweet and long.
