以下是《长恨歌》的原文及其翻译：

原文：

汉皇重色思倾国，御宇多年求不得。

杨家有女初长成，养在深闺人未识。

天生丽质难自弃，一朝选在君王侧。

回眸一笑百媚生，六宫粉黛无颜色。

春寒赐浴华清池，温泉水滑洗凝脂。

侍儿扶起娇无力，始是新承恩泽时。

云鬓花颜金步摇，芙蓉帐暖度春宵。

春宵苦短日高起，从此君王不早朝。

翻译：

The emperor, fond of beauty, sought the fairest maid.

For years he ruled but found no perfect mate.

From Yang’s family came a girl, now grown,

Nurtured in seclusion, still unknown.

Her natural charm could not be hid,

One day she caught the monarch’s eye.

A single glance and all would sigh,

Six palaces’ beauties paled by her side.

Spring chill brought her to Huaqing Pool,

Warm waters cleansed her skin like snow.

Attendants held her as she stood,

Newly graced with royal favor good.

Her hair adorned with golden pins,

Under lotus curtains she begins.

Spring nights were brief, dawn came too soon,

Henceforth the emperor missed his noon.
