U.S. first lady Michelle Obama and her family have just ended their one-week trip in China. The whole world has paid attention to the two elegant and beautiful first ladies who have made a difference in the relationship(关系) between China and the U.S.A.

Mrs. Obama has visited the Forbidden City, the Great Wall, the Terracotta Warriors, and the pandas. She has tasted Peking Duck and experienced some other Chinese traditional culture.

Today, the number of exchange students between China and the U.S. has reached more than 4 million every year.
