Polo served as a special envoy for Khan

He did the job well, and the Chinese monarch frequently used him as an envoy after that. Some of the places he traveled to had never been explored by Europeans before, and Marco Polo had many strange encounters with Asian tribes that were virtually unknown. He gained promotion after promotion. He served as the mayor of a major Chinese city for a number of years. Marco Polo, his father, and his uncle were all eager to go back to Venice at this point. They had all provided devoted service to Kublai Khan, which he had appreciated and rewarded with wealth, but he did not want to let them go.

The great Khan received the Venetians with great honor, and they soon arrived there. Kublai Khan, who had a special fondness for young Marco, appointed him as his envoy and gave him power. Marco Polo traveled to the Chinese provinces using this authority to complete a variety of tasks, mostly diplomatic ones. Through these journeys, along with his inherent curiosity and extraordinary memory, Marco was able to learn about the customs and way of life of the citizens of this mysterious nation and later to write a unique and descriptive account of his discoveries and impressions. He reportedly traveled by land from Bukhara to China. He mentions his trip to Samarkand in one of his "Book" versions.

He gave the leader insightful reports from the numerous journeys he made throughout Asia on his behalf. This included the three years that he spent overseeing Yangchow as the city's governor.
