Pu-erh tea

„Nèi piào (内票): A larger description ticket or flyer packaged loose under the wrapper. Both aid in assuring the identity of the cake. It usually indicates factory and brand. As well, many nèi piào contain a summary of the tea factories' history and any additional laudatory statements concerning the tea, from its taste and rarity, to its ability to cure diseases and effect weight loss.“

„Pu-erh shape - Bing, Beeng, Cake, or Disc - A round, flat, disc or puck-shaped tea, the size ranges from as small as 100g to as large as 5 kg or more, with 357g, 400g, and 500g being the most common. Depending on the pressing method, the edge of the disk can be rounded or perpendicular. It is also commonly known as Qīzí bǐngchá (七子餅茶, literally "seven units cake tea") because seven of the bing are packaged together at a time for sale or transport.“
