On the eve of the founding of the People's Republic of China, due to the inconvenient transportation, Chengde people rarely eat a meal of white flour. Small businessmen have made up their minds about the local specialty buckwheat noodles. These people use camels as transportation tools to transport buckwheat back from neighboring counties and process it into bowls.

At that time, there were many restaurants with buckwheat as their staple food in Chengde city. There are more than a dozen vendors around who also sell bowls. Because it is located in Erxianju, the old Chengde people used to call it "Erxianju Bowl Tuo".

In the Qing Dynasty, seven emperors, Kangxi and Qianlong, came to Chengde to hunt every year and stayed in the summer resort for half a year at most. Those princes, ministers and ladies-in-waiting also came with them. The concubines and ladies-in-waiting who lived in the villa at first told eunuchs to go out and buy the delicious bowl tuo in Erxianju. Later, the little boy who peddled the bowl tuo sent it to the palace. After a while, the value of Erxianju Wantuo increased greatly and became a very famous snack.

There is still a pun circulating in Chengde city that "the bowls of Erxianju are all fried (pointed)". It means not only that fried bowls are delicious, but also that people who sell bowls can do business.
