"Kǒu Xián Tǐ Zhèngzhí" is an original song featuring YANHE, Xin Hua, and Yuezheng Ling. The images were originally intended for a cover version of Bang Bang, but were used in this song instead. The title is a short form of the Japanese phrase "口が嫌だと言っても 体は正直なものだ" or "The mouth says no, but the body is honest".
