The female vocals in the harmony part of the song "Demeanor" are amazing. Wang Sulong increased the proportion of female vocal harmony, giving it more fresh tension. The entire arrangement is grand yet delicate, the bridge part has strong ups and downs, and the chorus melody is beautiful and catchy. Teacher Gu Su, a well-known musician in the industry and Wang Sulong's most frequent collaborator, plays the guitar in a sad but not sad manner, and handles emotions very well.
