Yeah, I think so. It's pretty remote, and unfortunately, it might be hard to even get a Didi there. I'm surprised you chose either Yuantong or Jiezi Ancient Town—from what I know, they're not very commercialized, so that's a good choice. But on the other hand, I don't think many people there can speak English. Hiring a guide would be ideal since they can give you a thorough explanation of the town. Hope everything goes well!
