Pu-erh tea shapes

„Pu-erh shape - Mushroom - Literally meaning "tight tea," the tea is shaped much like túocha, but with a stem rather than a convex hollow. This makes them quite similar in form to a mushroom. Pu'er tea of this shape is generally produced for Tibetan consumption, and is usually 250g or 300g.“

„The most classical Puerh Tea is the Bingcha, recorded in Yong-Zheng 13th year in Qing Dynasty (1735). Each tea cake weighs 7 Liang (357 grams). Seven cakes make 1 Tong (wrapped in leaves), weighing 49 Liang. It was sold in nice places and also was exported abroad. It was re-named as "Yunnan Qizi bingcha - Yunnan seven cake tea" during the Cutural revolution.“
