Twenty-Four Histories
He was the author of three of the "Twenty-Four Histories", writing the "History of Liao", the "History of Jin", and the "History of Song" (the three predecessor Chinese states to the Yuan dynasty). Later in life, he was falsely accused, banished, and murdered. Losing him, the Yuan court might have lost its last chance to defeat the Red Turban Rebellion, which started in the early 1350s against their rule. He was Bayan's nephew and Bayan Khutugh's brother.
