Great find.

The varieties of of tea shapes after processing are even greater.
Broadly speaking they can be classified further into three types:
broad/flat (e.g. dragonwell), rounded (e.g. gunpowder) and thread-
like. A Chinese tea book even classified them into eleven shapes -
just for green tea alone. Quite staggering.

Pretty much of the books I use are Chinese, and it is such a hassle to
order from China. Sorry wasn't able to give any references to help.
