When one thinks of Shanghai, the image that is presented to the world is the glistening Pudong skyline — a monument to the 21st “Chinese Century.”  But we stayed across the river in the more historic part of town, an area more akin to Greenwich Village or the Latin Quarter of Paris.  This is the French Concession and — perhaps more than anyplace we’ve yet visited on our journey — we felt at home.  This is the souvenir we took from our neighborhood in Shanghai that we didn’t want to leave.  (“Souvenir” is a beautiful word.  In French, it means “to remember.”)
