Lv Ye Cheng Yin (Green Leaves Make Fine Shade)
The Tang Dynasty poet Du Mu once went to Hu Prefecture. There he met an old woman leading a very beautiful young girl. Du Mu made the old woman promise that the girl would wait for him for ten years. After that, if he did not come to marry her, the girl would be free to marry somebody else. Then Du Mu gave the old woman a large sum of money as his betrothal gift and left. But 14 years passed before he returned. By then, he found that the girl had been married for three years and had already given birth to two children. In his sorrow, Du Mu wrote a poem called, "Melancholy of Separation":
In the quest for spring I met delay.
No need for sad resentment of the flowery season.
The winds have blown away the deep crimson.
Now the green leaves make fine shade.
And the boughs are laden with fruit.
Later, the phrase came to be used to describe a woman who has married and become the mother of many children.
