Disrespecting China’s national anthem could carry a prison sentence of up to three years under a new draft law amendment, which may also affect Hong Kong and Macau, state media reported Tuesday. Some football fans in the self-governing city have booed the Chinese anthem when it was played at matches, despite appeals for restraint. China has been fine-tuning legislation on the proper way and place to sing its national anthem, recently tightening rules that already bar people from performing it at parties, weddings and funerals.
