I once paid a brief visit China ten years ago and it was my dream to return someday. Travel the length of the country felt like a dream then. However, in 2017 it finally came truly. Not for a few weeks’ adventure, and to live and work for a year. It was an unique opportunity to experience many about the mysterious country. I would communicate with people from different backgrounds and have lots of funs. I was warmly welcomed the moment when I arrived at the college. I thought, “I am going to enjoy this.” It really go like this. Indeed, my students often ask, “Bruce, why are we always smiling?” What else could 1 say?
