放歌用少白韵，
Sing aloud with a few simple rhymes,
一百五日又欲来，
One hundred and five days will soon arrive,
千树万树梨花开。
Countless pear trees bloom with flowers.
眼看春色如流水，
As I gaze upon the flowing spring scenery,
人生相命亦如此。
I realize that human destiny is also fleeting.
百年三万六千朝，
A hundred years, thirty-six thousand mornings,
倏忽须臾难久恃。
In the blink of an eye, it is difficult to rely on them for long.
君不见十八羽林郎，
Have you not seen the eighteen feathered guards,
君王手赐黄金铛。
Whom the king bestowed with golden weapons?
日晚朝回拥宾从，
Returning from court in the evening, accompanied by loyal ministers,
片言出口生辉光。
Their every word resounds with brilliance.
一朝负遣辞丹阙，
But one day, dismissed from the crimson palace,
穷巷悄然车马绝。
They find themselves in a desolate lane, devoid of carriages and horses.
舞影歌声散绿池，
Their dancing shadows and singing voices scatter in the green pond,
遗垆但见狐狸迹。
Only fox tracks are seen at the abandoned tomb.
当时一旦擅豪华，
Once they enjoyed extravagant luxury,
见此空为人所嗟。
Now, people sigh at their empty state.
莫向尊前惜沉醉，
Do not hesitate to indulge in pleasures before the esteemed,
参差辜负东园花。
Uneven steps squander the flowers of the Eastern Garden.
