Actors dressed as characters from The Da Vinci Code spent a day at Shanghai’s Book City exchanging pirated copies of the best-selling thriller for legal editions. “Customers looking to turn their fake copy in for a legitimate edition had to tell the actors where and when they bought the pirated book. Since the Chinese version was published last year, 500,000 legal copies of the book have been sold, but pirated versions are still readily available throughout the country. The real book sells for about 28 yuan (US$3.38), while pirated versions sell for between 5 yuan and 10 yuan.”
