Just in case you were curious….
Kublai Khan was the grandson of Ghengis Khan. Along with providing religious freedom, he created aid agencies, increased the use of postal stations, established paper currency, reorganized and improved roads, and expanded waterways. Under his rule, the winter capitol was moved from Mongolian territory to the Chinese City of Dadu, which is modern day Beijing. He established the summer capitol in Shangdu, which was referred to as Xanadu. In 1275, Marco Polo, a Venetian explorer, visited Xanadu and a relationship of trust was formed between the two.
