Teach me some English and u can stay at my home

This entry is about China xD
During my trip before few weeks I read an interesting article in the Kuwait Airways' Magazine, I think its name was "Alburaq", Not sure ;/ but any ways the article said that some Chinese families started to work in a new project that allow them to host the tourists in their houses for free , and the tourists instead have to teach the family English Language for 1 or 2 hours daily, I don't know but I really liked the Idea so much, I feel that it is really interesting and it shows how important is this language, I think maybe the high costs of English courses in china forced them to start this thing but anyway it is not bad ...
