楚国的庄王听说越国在他的领地里修筑了城墙，于是他决定出兵攻打越国。他派遣使者向越国的国王提出要求，要求越国停止修筑城墙并向楚国道歉，否则就会发动战争。

越国国王并不愿意屈服于楚国的要求，于是他决定率领军队迎战楚军。两国的军队在越国的境内展开了激烈的战斗。最终，楚国的庄王决定撤军，因为他意识到自己无法战胜越国的军队。

这个故事告诉我们，无论是政治还是军事，都需要理智和判断力。在处理国家事务时，我们必须冷静地分析局势，权衡利弊，以达到最好的结果。

Translation:

Chu Zhuangwang, the king of Chu, heard that Yue Kingdom was building walls in his territory, so he decided to launch a military attack on Yue Kingdom. He sent envoys to the king of Yue, demanding that Yue Kingdom stop building walls and apologize to Chu, otherwise war would be declared.

The king of Yue did not want to yield to Chu's demands, so he decided to lead his army to fight against the Chu army. The two armies engaged in fierce battles in the territory of Yue. In the end, Chu Zhuangwang decided to withdraw his troops because he realized that he could not defeat the Yue army.

This story tells us that both political and military affairs require rational thinking and judgment. When dealing with national affairs, we must analyze the situation calmly, weigh the pros and cons, in order to achieve the best results.
