EDIT: According to Yunnan Sourcing, "Ba Jiao Ting" isn't the specific name for the tea, just for the brand. So I am thinking that the 901 would be this specific cake. YS also mentions that Liming factory is based out of Menghai, and that they have a good reputation.
The tea shop I bought it from specialized in puerh and had many really nice offerings, if I'd had more money to spend I would've picked up a couple others too. The owner of the tea shop was great, she was super helpful. At first she tried to sell me on a much more expensive cake, but after talking with her a bit in Chinese she helped me find a cake in my price range that she liked. We tried several different teas, including some quite expensive Fuding white tea. While my girlfriend and I were sitting there tasting this Liming, a middle-aged Chinese couple walked in and sat down to drink some tea as well. They seemed to be regulars, as the owner knew them personally. We talked with the couple for a long time, maybe an hour or two, and they said that they always came to that shop. They seemed to know their way around puerh, so this was pretty reassuring. The man talked with me about all sorts of things, particularly health and what tea does for your body, as well as other things like Tai Chi, international talk, life, etc.
They also had a bunch of Fuding white tea cakes there, which seems to be very popular in China at the moment (or at least in Chengdu). The white tea was great, I would've probably bought a cake of that too if I'd had the money. However I later ended up getting a Fuding white tea cake for free at a sort of tea demonstration thing in Shanghai. It was a gift because I was a student apparently, I didn't see anyone else there get one. This Chinese calligraphy professor (who incidentally became our tour guide there) dragged us all around the place showing us his calligraphy awards, different tea rooms, and other stuff, and right before leaving he brought us into this room with all these gift bags. Then he grabbed some for us
It's not as good as the white tea I tried at the shop in Chengdu, but it's still very good. Not sure about the value, perhaps something around 300-400 RMB? Really not sure.
) and have a couple shengs that once brewed up have almost more in common with a consommé than tea, e.g. an 2011 Autumn sheng from YangTa (JingGu). 
Was this really enjoyable? I can't tell.
