Encounter is a very unique textbook that I am using it this semester in Fudan-UC Exchange Student Program. I feel that it is more like a TV series rather than a textbook. Accompanied with this textbook are hours of video materials, comprising dramatic episodes, cultural segments, and animations all shot in China by Hollywood producers. It immerses learners in the Chinese language and culture through video episodes.
*In Dec. 2014, The Confucius Institute Headquarter reports that 54 languages and 1300 kinds of Chinese textbooks have been published in last decade.
