BERLIN (AP) — A prison cell, a pair of jade handcuffs and an installation built with rubble from a demolished studio: Dissident artist Ai Weiwei is drawing heavily on his troubles with the Chinese authorities at a spectacular new show in Berlin.

Ai has filled a floor of the Martin-Gropius-Bau museum with pieces large and small for his exhibition “Evidence,” which opened Wednesday and was billed by organizers as his biggest yet. Ai is barred from leaving China, but still made his presence felt unmistakably in the selection of works.
