Pu’er tea has the tradition of Yunnan Seven Sons Cake Tea. After being steamed and pressed, the taste of the tea becomes sweeter and moister, and it can be stored for a long time, locking in the flavor of the tea without loss. The packaging style adopts the earliest rubbing printing of texts since the 1950s for Yunnan Pu’er tea. The traditional Yunnan Pu’er tea cake weighs 357 grams. Here, certain convenient improvements have been made by changing it to 100 grams. The concept of “Enjoying tea while traveling(游山玩茶)” is to make it convenient to drink good tea.
