Answer:
The historians doubt Marco Polo's veracity of venturing into deep of China and Mongol as his accounts leave certain main descriptions such as the Great Wall of China, tea drinking, binding of women's feet, etc.
Explanation:
Marco Polo was an adventurer of the 13th century, who believed to have ventured across Asia. The accounts of his adventure to Asia is written in his travelogue which is published under the title 'The Travels of Marco Polo.'
Marco Polo ventured into the land of China through a route which later came to be known as Silk Route. Some historians like Frances Wood, questioned reliablity of Marco Polo's venture into China on the account of missing descriptions about China. 
They argued, that, if Marco Polo did really explored into deep of China and Mongol region then how did he not mention about the Great Wall of China. And the most baleful practice of binding of women's feet. And the tradition of drinking tea.
