The following are several carefully selected pieces of music for the poster to choose from. 1. The middle part of Guan Xia's "First Symphony Overture" is very good, relatively gentle, and the second half is more exciting. 2. Pure music like "Castle in the Sky" (Hisaishi Joe) is actually the most suitable background music for debate competitions or videos. 3. Tang nguoi toi yeu (singer) - You Can Trust In Me (song title) (This song is very nice, and it is also used as background music in large-scale debate competitions.)
