How did Jing Ke attempt to assassinate the King of Qin?

The "Records of the Grand Historian" (Shiji) and the "Comprehensive Mirror to Aid in Government" (Zizhi Tongjian) both document the story of Jing Ke's assassination attempt on the King of Qin. The "Shiji" details the background and aftermath of Jing Ke's mission, including how he prepared for the assassination, gained entry to the Qin palace, and what happened after his failed attempt when he was killed. In contrast, the "Zizhi Tongjian" primarily focuses on the process of Jing Ke's assassination attempt, providing a detailed account of the circumstances during the attempt and how the King of Qin managed to escape. Both sources offer valuable insights into this historical event of Jing Ke's assassination attempt on the King of Qin.
