The Pamiri people of Gorno-Badakhshan Autonomous Province in the southeast, bordering Afghanistan and China, though considered part of the Tajik ethnicity, nevertheless are distinct linguistically and culturally from most Tajiks. In contrast to the mostly Sunni Muslim residents of the rest of Tajikistan, the Pamiris overwhelmingly follow the Ismaili sect of Islam, and speak a number of Eastern Iranian languages, including Shughni, Rushani, Khufi and Wakhi. Isolated in the highest parts of the Pamir Mountains, they have preserved many ancient cultural traditions and folk arts that have been largely lost elsewhere in the country.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What group has not preserved any cultural traditions?
unanswerable
