在寇准的故事中，我们可以看到一位深谙天下之大势、善于运用成语来指导国家大事的宰相。寇准出身北宋，字平仲，以诗书闻名，曾任殿中丞、通判郓州等职。他不仅才华横溢，更以直言敢谏著称，在政治上获得了真宗的重视。在一次紧要关头，当契丹南下犯宋时，寇准力主真宗亲征，与参知政事毕士安同为宰相，他提出的“澶渊之盟”虽然遭到部分人的反对，但最终成功地维护了国家安全。

然而，不幸的是，在后来的宫廷斗争中，寇准再次被排挤，被贬至雷州和衡州 ultimately passed away in 1023. Throughout his life, he left behind many works, including the "Kou Lai Gong Ji" poetry collection.

In one of his stories, it is said that when Song Taizong was planning to establish a new heir due to the mental illness and violent behavior of his eldest son, Chu Wang Yanshan (元佐), he sought advice from Kou Quan. Kou Quan proposed that the emperor should secretly order the prince to attend a ceremony at an ancestral temple three days later with all his guards. Once there, a trusted eunuch would seize the opportunity to arrest him and confiscate evidence of his wrongdoing. The plan was executed without incident, and Yanshan was subsequently deposed as crown prince.

This story showcases Kou Quan's strategic thinking and ability to use historical idioms for guidance in state affairs. Despite facing challenges throughout his life, Kou Quan remained committed to serving the country with integrity and wisdom until his death in 1023.
