Cheung Ka-long’s 15-14 victory in an Olympic fencing final against Filippo Macchi has resulted in a war of words between their fans. Italy supporters have attacked Cheung’s social media accounts, arguing that the referees - from South Korea and Taiwan - may have been biased towards him. In response, Hongkongers have posted their love of ‘pineapple on pizza’ and ‘pasta with soy sauce’. Pizza hut Hong Kong has announced free pineapple toppings on pizza orders.
