In addition to learning more about Dungans while we were in Tokmok, we also learned a lot more about Uyghurs. I wrote a post about Uyghurs in Kyrgyzstan about a year ago near the time we left Tokmok and since then we've met a lot of Uyghurs in the second group I wrote about- people who came here in the last 50ish years. We live near the Uyghur quarter where many of them initially lived and our taxi drivers have often been Uyghur.
I didn't see much evidence of Uyghurs in Osh except for all the Uyghur restaurants around. Unfortunately I wasn't with a group who thought trying one of those places was the way to go. Uyghur food is the best.
I still think someone could do an amazing dissertation here by interviewing Uyghurs who left China in the 50s and 60s.
