"Dao" were revived during the Yuan dynasty. Circuits were demoted to the second level after the Yuan dynasty established provinces at the very top and remained there for the next several centuries. The Yuan dynasty also had "lu" (sometimes translated as "route"), but it was simply the Chinese word used for the Mongolian administrative unit, the "cölge". The Yuan "lu" had little to do with the circuits ("lu") in the Song and Jin dynasties and were closer in size to prefectures.
