In this week's Dear Amber one of our listeners, Arthur Cookson, who is a self-proclaimed "Beijingren", joins us with a tale of two Chinese cities. Plus, Amber is on a diet after a food-filled visit to a local friend's place for lunch, and Jenny gives us some guidance on how to be a good guest at your Chinese friends' home. Visit us in the comments section too and share your stories and views on what we talked about today.
