Chang' an ancient music, dream back to Datang and pure music of 12 girls band are all classical music ~ ~ which is more suitable for the classical atmosphere of Xi' an. BlackHead's songs are cheerful and suitable for introducing local specialty snacks in Xi' an ~

I think we can match classical music with the previous slides, and finally match it with a video introducing Xi' an specialty snacks with Heisa, so that everyone can not only understand Xi' an's culture but also its characteristics.
