Chinese learning demand in US grows

CHICAGO - When Ren Yi began teaching Chinese in the US city of Denver over 20 years ago, she never thought she would become a popular author of Chinese language textbooks.

"My self-made Chinese textbooks have been sold through Amazon and other sales channels, so far the feedback is very positive," says Ren.

Standing in a booth at the recent annual convention of the Chinese School Association in the United States in St. Louis, Missouri, Ren greets the attendees.
