No, just considering Lancang district as a whole. Easier that way, because of the way regions bleed into one another. A couple of JingGu are way the heck sure on Ai Lao Mountain on the eastern edges of JingGu county. I do get confused with Qianjiazhai since I think that's in Zhenyuan county, and still some people sez that's a JingGu. Not sure, as with Osanzhai.
Mengla county doesn't really have overlapping mountains. Longpa (the only Youle that matters, it seems) is well away from the eastern most Menghai tea which would be Pasha, I think. Or Gelenghe. There are no really worthwhile Yiwus up at the lancang border, nor Yibang et al. The only overlapping border is GFZ and Laos. Menghai county is pretty much the same way. Only one tiny spot to its north, well defined spots to the west, and one overlapping area to the south where Damenglong is, with Burma.
Lancang has its issues, but there just aren't huge plantations of high quality teas there, so it's not too much of a confusion. Jingmai, Bangwei, Kunlu, Xiao JingGu + Yangta, and Qianjiazhai. Beyond that, Jingmai is the only place with *large* ancient plantations. Everywhere else is tiny.
Lincang is crazy, and is dominated by the fact that there are *two* DaXueShan. One of them is a ridge that goes from Yongde to Fengqing, and it's material *where* on that DaXueShan we're talking about. However, very few places in Lincang have distinct villages labeled on that bing wrapper, and if you find one of those old price lists from 2007 or so, you'll find that there are a number of villages where price per leaf is pretty expensive, but you've never heard of any of them. Bingdao/Xigui, functionally, is a scam and and an idea rather than any concrete idea of tea, unless we think of it as a premium region, like describing Yiwu teas. This all makes it very hard to narrow in on what Lincang teas you really like.
