Designed by I.M. Pei, the Suzhou Art Museum opened in 2006, timed to celebrate his 90th birthday. [The inaugural exhibition included work by three contemporary artists who like Pei left China to work or study abroad: Cai Guo Qiang, Xu Bing and Zhao Wuji]. Tapping my shoulder, old Pei would always say: “How youthful you are, you walk so fast!” Courtesy of the artist
