This sentence came from the Tang Dynasty poet Li Bai's poem," The Wine Will Come." The whole sentence is "Do you not see the water of the Yellow River flowing from heaven to the sea and never returning?" Can't you see the bright mirror in the high hall sad, white hair in the morning like black silk, turning into snow in the evening? Life is full of joy, do not let the golden cup empty face the moon. I'm born with talent, I'm sure it'll be useful. To cook sheep and slaughter cattle for fun, you must drink three hundred cups at a time." Among them, the poem "Tears on the moon and pearl in the vast sea" was not the original content of the poem, but a sentence added by later generations to express the poet's sad feelings.
