原文：

天地有正气，杂然赋流形。

下则为河岳，上则为日星。

于人曰浩然，沛乎塞苍冥。

皇路当清夷，含和吐明庭。

时穷节乃见，一一垂丹青。

翻译：

The world is filled with righteous spirit,

Which takes various forms and shapes.

Below it becomes rivers and mountains,

Above it turns into the sun and stars.

For people, it is called grandeur,

Overflowing to fill the universe.

When the imperial way is clear and peaceful,

It breathes harmony and shines in the bright court.

In times of crisis, true character emerges,

And these virtues are forever recorded.

通过这首诗，文天祥不仅表现了自己对国家的忠诚，也激励后人坚守正义与真理。希望这些诗句能够激励我们面对困难时保持坚韧不拔的态度。
