The origin of "green, leisurely my heart" in Cao Cao's short songs

The source of Cao Cao's The Book of Songs is The Book of Songs Zheng Feng. This poem is about a woman waiting for her sweetheart on the tower, but she can't see him. She kept walking back and forth in a hurry. A day's absence is like three months.

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!

Green is your collar, and leisure is my mood. Even though I didn't go to see you, didn't you receive my letter? Green is what you wear, and leisure is what I miss. Even if I didn't pick you up, couldn't you come voluntarily? Come and go, look around, on this tower. I haven't seen you for a day, like three months!
