The Book of Songs Zheng Feng Ji Zi

Qingqing is your collar, YY is my miss.

If I didn't go to see you, didn't you get my letter?

Green is what you wear, and leisurely is my feeling.

If I never visit you, can't you take the initiative?

Come on, always open your eyes, on this high tower.

A day without seeing your face seems as long as March!
