„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.“
