"Emperor Qin Shi Huang travelling in a palanquin", a 18th-century Chinese painting. #ChineseHistory
During the regime of Qin Shi Huang, there were lots of officials from the other 6 states that were previously conquered swore revenge and tried to assassinate the tyrant emperor. In 218 BC, an aristocrat Zhang Liang sold all his valuables and used it to hire a strongman assassin and built him a heavy metal cone. The two men hid among the bushes along the emperor's route over a mountain. At a signal, the muscular assassin hurled the cone at the first carriage and shattered it. However, the emperor was actually in the second carriage, as he was travelling with two identical carriages. Thus the attempt failed and both men were able to escape in spite of a huge manhunt.
Also, there's another assassination plot where 2 envoys from Yan state went to the emperor one day. The first envoy tried to present the map case gift, but trembled in fear and moved no further towards the emperor. So the second one, named Jing Ke, continued to present the gifts by himself. While unrolling the map, a dagger was revealed. The emperor directly stood on his feet, but struggled to draw the sword to defend himself. Jing Ke pursued the emperor, attempting to stab him, but missed. The emperor drew out his sword and cut Jing Ke's thigh. Jing Ke then threw the dagger, but missed again. Suffering 8 wounds from the king's sword, Jing Ke realized his attempt had failed and knew that both of them would be killed afterwards. #PartFive
