McJaiwen's protegee, Chen Siwei, is promoted by her record company Jiayin Records as having singing skills surpassing those of Joey Yung. Her first EP has already been released. Chen Siwei was originally a newcomer from an inland film academy. In the movie *Gangster*, besides playing a minor role, she also sang the theme song, reinterpreting Sam Hui's old song "Keep the Sorrow to Myself" with a brand-new jazz rendition, fully expressing the sadness of the movie. Her ethereal voice interprets the theme of *Sister Ah传奇* in a sorrowful and plaintive way, leaving listeners unable to calm down for a long time after listening.
