Marco was amazed by how beautiful China was．He was impressed bu Beijing and the Emperor's Palace，especially the Summer Palace which he described as "The greatest palace that ever was…"The walls were covered in gold and silver and the hall was so large it could easily seat 6，000people for dinner．"

There were inventions and developments in China which couldn't focused in Europe at that time．Marco was surprised to see Chinese people using paper money in the markets．In Europe，people paid for goods with gold and silver．He could not understand how people pay for food and valuable things with paper! He was also puzzled by the black stones people used to burn to produce heat．The black stones were coal，but Marco had never seen coal before!

In 1291，after 17years of service to the Emperor，Marco returned to Italy．He was now a very wealthy man．A writer wrote down all the stories that Marco told him in a book called The Description of the World，which became one of the best﹣selling books in Europe．

Although people enjoyed reading the book，many of them thought that Marco's stories about China were too fantastic to be true．But Marco always stood by his tales．Just before he died，aged 70，Marco was asked the question，"Was it all true？"And this was his answer："I have only told a half what I saw!"
