This spring, an American named Sarah Randy wrote to President Xi Jinping to thank him for his precious friendship with an old friend.

Soon, President Xi wrote back to Randy, encouraging her and her old friends in Iowa to continue to sow the seeds of friendship and make new contributions to the friendship between the people of China and the United States.

  The two letters spanned the other side of the ocean and carried the 37-year friendship between Xi Jinping and old friends in Iowa.

What is the story of President Xi and Iowa on the Mississippi River? Let us experience this warm friendship together.
