Puerh History - Pu-erh.Net

„Head Tea (aka Golden Melon) is shaped like a ball, weighing between 2 Liangs and 10 Jins ( 1 Jin = 500 grams). They were mainly for domestic trade or serving as tributes to emperors. Stacks of Golden Melons progressing in size from gigantic to small are considered to be a status symbol.“

„At the beginning of 1990s, many small tea factories were born. Some of them started to use class level 3 (or even higher) raw tea (which was only available for emperors in the past) instead of level 6 (or even lower) raw tea (which was the traditional material for producing Pu Erh Tea).“
