1, all kinds of tea have different shapes. For example, frozen top tea is hemispherical, Tieguanyin is spherical, Wenshan packaged tea is strip, and Longjing is flaky.

2. The color of tea is mainly bright, oily and shiny, and the color is uniform. Except Longjing is green, everything else is frog skin color.

3. The better the tea strips, the better. Because the more tender the tea leaves are, the more knotted the cords are.

4. The body and bones are better. Because the young leaves are thick, the tea strips are strong, and the old leaves are thin and loose, which is lighter than ordinary tea leaves. The rope has good integrity and similar thickness and size.

5. The drier the tea leaves and tea stems, the better.

6. The longer the fragrance stays, the better. If there are other odors such as "burnt smell", "smoky smell", "sour smell" and "musty smell", or mixed odors such as turbidity, it is inferior.

7, the entrance feels mellow and smooth, and it can make the tea fragrance linger in the mouth for a long time.

8. Tea soup tastes bitter, light, or stinks of flowers, all of which are inferior. If bitterness is only a short-lived phenomenon, it is no harm to return to sweetness immediately.

9. The less sediment in tea soup, the better.

10, the color of water is strong and bright, and it is not good if it is turbid and dim.
