Pu-erh Tea Cake is a round, flat, disc or hockey puck-shaped tea. Size ranges from as small as 100g to as large as 5kg 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. Also commonly known as Qizi Bing Cha (literally "Seven units cake tea") due to the fact that seven of the bing are packaged together at a time for sale or transport.
