In the seventeenth year, Gengchen (1280), in the sixth month, the new calendar was completed and bestowed the name Shoushi (Granting Seasons). The next year it was first promulgated throughout the realm. An envoy was dispatched to trace the source of the Yellow River; traversing from the Xingxiu Sea to the Kunlun Mountains, he reached its location. Dou Mo was easygoing and affable by nature; in daily life he never once spoke ill of others. He rose to the rank of Academician and passed away at this time. He was posthumously named Wenzheng.
