"Genghis Khan has become a cultural phenomenon across the globe," he says. "The books I've collected show that many overseas scholars have abandoned stereotypes in recent years and have gradually come to consider him an early advocate of globalization, which echoes with modern times."

In 2003, Baljinnyam published his first book, Genghis Khan in the Eyes of the World's Famous Figures, to summarize different opinions on the ruler. But he says it is more important to have original viewpoints rather than just echoing other people's thoughts.

He has published 12 books so far, and several are on his own explanation of The Secret History of the Mongols, which was written for Mongol royal families after Genghis Khan's death and is generally regarded as the most significant native Mongolian record of the emperor's life.

In 2013, he opened a private museum in Hohhot to exhibit his collection.

Baljinnyam says both his daughters are busy running their own businesses, and have little time for this.

But he acknowledges his daughters' focus on their careers helped to sponsor his travels abroad.

He has reached an agreement to move most of his collection to the new Genghis Khan Literature Museum.
