In his short poems, Cao Cao used the poems from The Book of Songs Zheng Feng Ji Zi.

Qingqing is your collar, YY is my miss. Cao Cao is a politician, strategist, writer and poet. In short songs, he used the poem "Zheng Feng Ji Zi" in the Book of Songs, which was graceful and graceful. The Book of Songs Zheng Feng Purple Tune: The green purple tune is lingering in my heart. 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!
