Our landlords are fascinating people: anthropologists who used to teach at Tulane University. While their area of expertise is Mayan astronomy, they have lived all over the world and are both multi-lingual. Our landlady was born in Shanghai while her father worked for the U.S. state department, and during World War II her family was detained in a Japanese concentration camp (years later, one of her students revealed that his father had been a guard in the same camp, and brought his father's old uniform to class, bringing closure to this period in our landlady's life). Armed with her address in the old French concession and a few photographs - some from the 1940s and others from the 1990s, when other neighbors on the street also visited Shanghai and made the pilgrimage - we talked our guide into bringing us to the house.
Also in Shanghai: some sight-seeing and some shopping, including buying some really lovely pearls and silk, two products Shanghai is known for, and both available at incredible prices.
And thus concluded our China trip. It was a whirlwind, with a lot of travel, but worth it: these sights are precious history, and at the rate that China is changing, may not be the same forever.
