Everything in this garden is rosy

A new coloring book has become the rage among adults, because they believe coloring in the pictures helps them relax. But are they right? asks LI YANG

A coloring book for grown-ups, Secret Garden, by Scottish illustrator Johanna Basford has sold more than 1 million copies in China since in June, becoming the bestseller with the fewest words - only 264 Chinese characters - according to Hinabook, its first Chinese publisher.

Describing herself as "an illustrator and ink evangelist who prefers pens and pencils to pixels", Basford said in an interview with NPR early this year: "I think there's something quite charming and nostalgic about coloring in."
