Members of the former Duan imperial clan were appointed as governors-general with nominal authority using the title "Dali chief steward" (, p "Dàlǐ Zǒngguǎn"), and local leaders were co-opted under a variety of titles as administrators of the region. Some credit the Turkoman governor Sayyid Ajjal Shams al-Din Omar with introducing the system into China. Duan Xingzhi, the last king of Dali, was appointed as the first local ruler, and he accepted the stationing of a pacification commissioner there. Duan Xingzhi offered the Yuan maps of Yunnan and led a considerable army to serve as guides for the Yuan army. By the end of 1256, Yunnan was considered to have been pacified.
