This morning, your sightseeing starts with a stroll along the Bund, the city's riverfront boulevard lined with historic buildings, housing, banks, and trade houses. Visit YU YUAN GARDENS, dating back to the Ming Dynasty, and a SILK FACTORY to learn about the silk-making process. Then, take a WALKING TOUR of the former French Concession, once Shanghai's leading residential and retail area. Today, the qualities that made the area so popular endure-from quaint, tree-lined streets and exquisite architecture to charming shops and fashionable restaurants and bars. Stop at a local restaurant for lunch featuring XIAOLONGBAO, Shanghai's most famous dumpling dish. The remainder of the day is at your leisure. You may consider joining an optional tour to see a spectacular acrobatic show. (B/L)
