According to Netease Cloud Music, "Dream Back to Datang" was originally sung by Hao Meng, and the release date was February 22, 2023. The lyrics are written by Chen Ruijun and composed and arranged by Yang.

Part of the lyrics are: say a word about Chang 'an, Zhou, Qin, Han and Tang, and say a few words. Roar for a while, and a bowl of paomo has a long aftertaste. Huashan talks about swords, Xiyue fairy palms, and endless stories of morning bells and drums, Zhou, Qin, Han and Tang Dynasties.
