There are many grades of tongue, such as super grade, first grade and so on. The specific quality of different grades of finches varies greatly. The higher the grade, the lower the tea yield and the earlier the picking time, so the higher the price is understandable. Ordinary tea with large output is much lower.
Another factor that affects the price of sparrow tongue is the specific production year. Usually, the longer the year, the higher the quotation, and the earlier the production time, the lower the price. Therefore, when selecting, we must also look at the year of production.
