The top supporter in Jiang Xiangyi's live stream, with a level 50 purple ID that requires 1 million points to reach. Sing attends every stream but rarely speaks, quietly listening and spending money generously. Sing sent two Happy Fortresses (the most expensive gift on the platform, each worth five thousand) during the stream. Jiang Xiangyi assumes Sing is a girl since 80% of his fan base is female, but their gender is unknown. Sing occasionally sends messages like 'Not happy?' and 'Cheer up.'
