Meaning: You can't be a teenager forever in life. When you want to have a drink, don't be stingy with the money you spend to buy wine at the bedside.
You can’t grow young in life, so don’t waste the money you spend on drinks at the bedside. This poem comes from "Song of Hollyhocks" written by Cen Shen of the Tang Dynasty. It expresses that the poet wants us to cherish time, do what we should do, and not waste time worrying about gains and losses. He hopes that when we grow old, we can look back on our lives without any regrets.
