荊軻
The earliest reference to a map in Chinese history can be found in Volume 86 of the historical text "Records of the Grand Historian" ("Shi Ji"). This volume recorded an incident in 227 BC during the late Warring States period in which a map is mentioned. Crown Prince Dan of the Yan state sent Jing Ke to assassinate the King of the Qin state, so as to prevent Qin from conquering Yan. Jing Ke pretended to be an emissary from Yan, and said he wanted to present the King of Qin with a map of Dukang, a fertile region in Yan which would be ceded to Qin in exchange for peace between the two states. The map, which was rolled up and held in a case, had a poison-coated dagger hidden in it. As Jing Ke was showing the King the map, he slowly unrolled the map until the dagger was revealed, and then seized it and tried to stab the King. The King managed to escape unharmed and Jing Ke was killed in his failed assassination attempt. From then on, maps are frequently mentioned in Chinese historical texts.
