Hi Thomas,
How is everything with you recently? I'm very exciting because I have applied for a holiday job, taught English conversation in a teacher training college near Shanghai. I'm a bit of worried because I don't know if I should bring some present for the teachers I'll meet. Should 1 shake hands when I meet people, or just smiling? What topics will my students want to talk then? Might I say or do something that will seem rudely? This may seem unimportant with you, but I want to plan everything in advance, or I'd love to know what you think. You had been to China before.
Looking forward to your reply.
All the best,
Bruno
