Wang Wei and her husband, Liu Yiqian, are voracious collectors of Chinese art, both contemporary and traditional. The first Long Museum opened on the Pudong side of the river, in the suburban neighborhood of Jinqiao; the second is located on West Bund, a mere 15 minutes’ walk from the Yuz Museum. The building, done by lauded Shanghai architects Atelier Deshaus, might just stun you, with its enormous ceilings and open rooms that flow one into the other. Most exhibitions are of Chinese artwork—past shows include a retrospective of the work of cartoonist Zhang Guangyu and a selection of Qing Dynasty paintings. But big-name Western artists also show here, among them James Turrell and Olafur Eliasson.
