Mandarin Camp We are happy to announce an extended second session of Mandarin Camp 2015. We will have a 13D/12N session of our Mandarin Camp — Happy Sheep — November 23 to December 5. The camp is conducted entirely in Mandarin for native speakers and Chinese learners alike! Campers in the Mandarin Camp will have the same experience as our summer camp participants. Campers rotate through our core adventure activities and live in safari-style tents in the mountains of Wanli.
