Hi - I visited China twice last year for the Canton Fair - in April and October - very smoggy in Guanghzhou - I love China - it really is so high tech. I don't think people in the West really have a clue how high tech it is unless they go there. I feel as though in Australia we are like the Flintstones by comparison (you are young - you will need to Google the Flintstones reference). Love your travel blog on China
