“Waste Not,” said the Chinese painter Wu Hong. “For an everyday object to become a work of art, it is necessary for it to embody meaning, so even the most common things and image could be attributed with artistic value.” Wo Hong’s emphasis on humble materials has been an imperative among Chinese artists ever since the late 1970s, when many started transforming quotidian objects into powerful autobiographical sculptures. A miniature house made of wood and candles. A large rug made of real bananas. Satirical maps. The work of eight artists is on view. —E.C.
