A friend in Beijing recently reported an exchange with his Chinese tutor to me that went something like this (embellished by my own imagination and translated into English):
Friend: So today I’d like to talk about the air quality in Beijing.
Tutor: I really don’t want to talk about that. You foreigners come to China, and all you want to talk about is how bad the air is, or how the food is unsafe. There’s really a lot more we could talk about. China is an immense country with a long history and rich culture. We don’t even have to talk about China. There’s so much more we could talk about than just complaining about the air quality here.
Friend: I’m hiring you to help me improve my Chinese, and I want to talk about Beijing’s terrible air quality. So that’s what we’re talking about today.
Unsurprisingly, it wasn’t the greatest tutoring session. But just that little piece of dialog recounted by my friend contained quite a few layers of cultural expectations. (A thoroughly enjoyable exchange, from my perspective!)
