It's okay not to know today, and it's not shameful. Chinese tea culture is vast and profound. Even foreigners say, "One tea, one moment; one leaf, one universe." The most important ways to improve knowledge are studying and not being ashamed to ask. Learning tea culture is also quite challenging. Today, we summarize 20 small pieces of tea knowledge. As a tea person and a tea lover, you should indeed master them.

1. Drinking tea immediately after a meal does not aid digestion; instead, it can affect it.

2. Raw Pu-erh tea will not become ripe Pu-erh no matter how long it is aged; ripe tea is a result of processing, not time.

3. Not all teas are better when fresher; they need to lose their "fire" or "coldness" to be nourishing.

4. Black tea is not dark tea; it is red tea.

5. Chrysanthemum tea is made from flowers, not tea leaves.

6. Don't believe the first infusion is beneficial for the body; rinsing it is healthier.

7. Drinking tea does not cause calcium loss; on the contrary, moderate tea consumption aids calcium absorption.

8. Dongting Biluochun is produced in Dongting Mountain, Jiangsu, not Dongting Lake in Hunan.

9. Anji White Tea belongs to the green tea category, not white tea.

10. Da Hong Pao belongs to oolong tea, not red tea.

11. For jasmine tea, having visible flowers isn't necessarily better; it's tea, not flowers.

12. Junshan Yinzhen belongs to the yellow tea category, not white tea.

13. Oolong tea is green tea (Qing Cha); no matter how dark it is, it's still "green" tea.

14. Beigang Maojian and Weishan Maojian are yellow teas, not green teas.

15. Matcha is tea powder made by a special process, not just ground green tea.

16. Aged Pu-erh tea can be very valuable, but it's not necessarily made from ancient tree leaves.

17. Yunnan Moonlight White is a white tea, not a Pu-erh tea.

18. The commonly mentioned "Liu'an Tea" usually refers to a dark tea, not the green tea Liu'an Guapian.

19. Pure material ancient tree tea does not mean no blending; blending is absolute, purity is relative.

20. Pu-erh tea is not more valuable just because it's older. Garbage from 100 years ago is still garbage today.
