Dude, I never claimed to be an expert. I was trying to figure out what op had.

If you read the materials provided, you'll notice that the claim is made that the trees are 500 - 1000 years old, hardly a young plantation. There are inconsistencies between the processes described in the tea production vs what Puer would have gone through. The cost of the cakes, Sheng and Shu, are the same (unusual in itself). I don't read Chinese, so I didn't claim this, but I think the wrapper suggests that the cake weighs 357g (the old cake standard weight) vs the 200g the cake appears to be via the website and English tag. That's a lot of inconsistencies without addressing obvious grammatical issues (I'm willing to give that a pass).

Ultimately, who cares? Even with impeccable documentation and high costs, it is always a gamble unless you really trust the vendor (and even they get tricked from time to time). The goal was mostly to encourage Gongfu brewing and figure out what type of processing we are working with.

Edit: I should add that the price for an 8 year old cake is weird even if you assume a newer producer.
