Moses last walked on Gaoyang Road in 1947. It was called Chaoufoong Road then, and it was home to many of the 18,000 European Jewish refugees who had sought refuge from Nazi Germany in Shanghai's Hongkew District (today known as Hongkou) during the run-up to World War II. He casts his gaze at the lane, his brow loosens and he begins to nod. "This is it, this is it," he says softly. "I know this is it." One week into his first visit to Shanghai in almost 60 years, Moses has found his third home in an exile that lasted from 1941 to 1947.
