Yu Garden is a classical Chinese garden with over 30 pavilions linked by a maze of corridors and bridges over ponds. The Huxining Teahouse, within the garden, is said to be the model for the "willow-pattern" design used on Chinaware.
Chinatown is the rebuilt Old City around which modern Shanghai grew. It's now a popular spot for foreigners and locals to shop, bargain, and hustle.
