The Chinese Communist Party regime has always been censorious. Its so-called ‘Great Firewall’ means that Facebook, Twitter and Google are blocked in China, many are films banned and even Winnie the Pooh was persona non grata after netizens spotted his resemblance to Xi Jinping. In the Chinese version of Bohemian Rhapsody, references to Freddie Mercury’s sexuality – an important part of his story – are purged.
