闲话 #3: The 1st Raozhu Contest Announcement
Hello, Zhuoying!
We're Insect Academy of Sciences, a team researching mathematics, physics, and competitive programming.
Recently, we've observed a decrease in physical strength and enthusiasm for exercising among students at Zhuoying Middle School. In order to promote traditional culture and train physical fitness, we will hold the 1st Raozhu Contest. And this is the announcement of the 1st Raozhu Contest.
Background: The History of "Raozhu"
轲既取图奉之，发图，图穷而匕首见。因左手把秦王之袖，而右手持匕首揕之。未至身，秦王惊，自引而起，绝袖。拔剑，剑长，操其室。时恐急，剑坚，故不可立拔。
荆轲逐秦王，秦王还柱而走。群臣惊愕，卒起不意，尽失其度。而秦法，群臣侍殿上者，不得持尺兵；诸郎中执兵，皆陈殿下，非有诏不得上。方急时，不及召下兵，以故荆轲逐秦王，而卒惶急无以击轲，而乃以手共搏之。
是时，侍医夏无且以其所奉药囊提轲。秦王方还柱走，卒惶急不知所为。左右乃曰：“王负剑！王负剑！”遂拔以击荆轲，断其左股。荆轲废，乃引其匕首提秦王，不中，中柱。秦王复击轲，被八创。
