"Xià Yí Zhàn. Yǔ Nǐ" is an original song featuring Xin Hua and it is made for the Kaohsiung City metro. It's about someone who loves to travel and see new things, and enjoys traveling with his/her friend/crush through the Kaohsiung City metro. All the while, they are wondering about whether the other person is looking forward to anything in particular and asking many questions regarding what love is.
