The article discusses some examples of literary monuments and the history of Persian-Tajik and Uzbek literary ties. A number of studies have been carried out on the history of political, trade, economic and cultural cooperation between the ancient Turks and Sogdians. In the textbooks and methodological manuals prepared by our literary critics, we can find a brief overview of Sogdian literature, namely, some information about the Rustam epic. But other examples of Sogdian literature found in the Dunhuang region of China in the last century have not been carefully studied in terms of literary connections.
