"Treasures from Shanghai: 5000 Years of Chinese Art and Culture" (2007) featured objects on loan for the first time from the Shanghai Museum portraying the evolution of Chinese technology, art, and culture. Curated by Chen Kelun, authority on Chinese history and culture and deputy director of the Shanghai Museum, the focus of the exhibit was the ancient Chinese bronzes from late Xia to early Han dynasty, and Chinese porcelains from the Song dynasty to the prime time of the Qing dynasty. This was the third collection brought to the United States from the Shanghai Museum and the first in more than 20 years.
