A well-known Taiwanese rock band, Mayday, has refuted accusations of lip-syncing in China, where such practices are prohibited. The denial follows a Chinese authorities' investigation prompted by a viral video. Chinese commercial regulations prohibit lip-syncing before paying audiences, considering it deceptive, although enforcement is infrequent. Social media users in China questioned why Mayday is being singled out when lip-syncing is believed to be widespread, even on state television.
