For two decades China’s brightest students have flooded westward for university. Those who returned from their education in America, Canada or Britain were often held in high esteem and paid handsomely. But no longer. Returnees are increasingly looked at suspiciously by employers, who fear they could be unruly, or even spies. Meanwhile Chinese universities are climbing the global rankings. Chinese students’ waning interest in studying abroad will cause pain both at home and in the West.

Elsewhere, a handful of new films add to Hollywood’s obsession with pairing older women with younger men. The dynamic has intrigued screenwriters for decades (think of Mrs Robinson). But what is notable about the current cinematic trend is that similar relationships are increasingly happening off-screen, too.
