As another trip to China draws to a close, I leave this time from Shanghai Pudong Airport. Apart from the excitement of a trip on the Maglev (finally, after three years my itinerary allowed it!), the real thrill was finding a Lego Architecture set in the Duty Free of one of the great World Heritage Sites: the Great Wall of China. What’s not to like (apart from the price, which is as steep as the climb up parts of the Wall)?
