An architectural triumph, this IM Pei–designed museum is a modern interpretation of a Sūzhōu garden, a confluence of water, bamboo and clinical geometry. Inside is a fascinating array of jade, ceramics, wooden carvings, textiles and other displays, all with good English captions. Look out for the boxwood statue of Avalokiteshvara (Guanyin), dating from the republican period. No flip-flops.
