Director savors crazy comedy about sanity

Rao Xiaozhi will never forget a news story he read online in 2010, about a bus driver in Italy transporting three patients to a psychiatric hospital. When the driver stopped to get some drinks, the patients escaped. Afraid that he would lose his job, the driver grabbed three people from the street and took them to the hospital.

It took the hospital staff nearly a month to figure out that the patients were actually healthy people.

"How do you prove that you're not insane in a psychiatric hospital?" Rao, the pioneering theater drama director, asks.
