His story is told in the chapter titled Biographies of Assassins (刺客列傳) in Sima Qian's Records of the Grand Historian.

[4] There Jing Ke accepted the hospitality of Prince Dan, who, as a last resort, decided to send an assassin against the King of Qin.

[2] According to events at the time, Dukang (督亢) (in present-day Hebei Province) was the first part of the Yan state that the Qin wanted, by reason of its fertile farmland.

Fan Yuqi (Huan Yi) believed that the plan would work, and agreed to commit suicide so that his head could be collected.

[6] Concealing the dagger inside the map scroll, Jing Ke and Qin Wuyang represented the Yan as ambassadors and met with King Zheng.

[6] Qin Wuyang reportedly became so nervous that he acted almost paralyzed when entering the palace, and Jing Ke managed the excuse that his partner had never set eyes on the grace of Son of Heaven.

[8] Other sources suggest Jing Ke described Qin Wuyang as a rural boy who had never seen the world and was suffering a cultural shock.

None of the other Qin officials within the vicinity were armed and able to stop Jing Ke, and the guards were all stationed outside the palace and were unable to immediately reach the scene.

Knowing it was hopelessly over, the dying Jing Ke sat with his legs stretched forward and apart (a posture then considered very rude), and used the last of his strength to taunt King Zheng with abuses.

[9] It was recorded that right after the incident, King Zheng sat on his throne catatonically holding the sword due to the exhaustion caused by the adrenaline rush, before he finally recovered after a short while and thanked the physician Xia Wuju for attempting to stop the assassin.
