Li BaiTo wash and rinse our souls of their age-old sorrows,We drained a hundred jugs of wine.A splendid night it was . . . .In the clear moonlight we were loath to go to bed,But at last drunkenness overtook us;And we laid ourselves down on the empty mountain,The earth for pillow, and the great heaven for coverlet
Li BaiBears, dragons, tempestuous on mountain and river, Startle the forest and make the heights tremble. Clouds darken beneath the darkness of rain, streams pale with a pallor of mist. The gods of Thunder and Lightning Shatter the whole range.
