At the last PPP one of the gals sheng samplers was 'crab feet' from PuerShop. I was familiar with Hairy Crab oolong and previously heard of crab feet puer. I got this picture from TaoBao.

What struck me was the name of the factory Yun Pu like Yun(nan) and Pu (er). The romanization should read Yunnan Kunming Yun Pu Tea Factory to match the characters. I dont know but could this be one of the first puer factories in Yunnan.
PS The pictures of the cake veneer on TaoBao was interesting also. There were long broad wide strips that didnt look like leaf along with noticeable leaf.
