When I first arrived in Paris, maybe it was rainy, or maybe it was too early. Arrive at Charles de Gaulle Airport at 6 o'clock. Compared with domestic and Hong Kong airports, this is a level 2,3 city airport. The whole journey of Paris is basically in the old city, the specific number of districts can not remember. But everywhere is full of art and history. It's really a city that makes people wander around.
