Lifting my head to look, I saw the moonlight. Sinking back again, I thought suddenly of home.
举头望明月，低头思故乡。

You don't see that the Yellow River's water comes from the sky .It rushes to the sea and will never return .
You don't see the person is sad when he sees his gray hair in the bright mirror in the big hall ,It was black in the morning and turned into gray in the night .
We should enjoy ourselves when we are in success ,and don't only hold a golden but empty cup under the moon.

静夜思 李白 床前明月光，疑是地上霜。 举头望明月，低头思故乡。

1).In the Still of the Night I descry bright moonlight in front of my bed. I suspect it to be hoary frost on the floor. I watch the bright moon, as I tilt bac k my head. I yearn, while stooping, for my hom eland more.

　　静夜思
　　李白
　　床前明月光，疑是地上霜。
　　举头望明月，低头思故乡。

　　1).In the Still of the Night
　　I descry bright moonlight in front of my bed.
　　I suspect it to be hoary frost on the floor.
　　I watch the bright moon, as I tilt back my head.
　　I yearn, while stooping, for my homeland more.
