Introduction to the hanging sword picture: When Ji Zha was on his first mission to the state of Xu, King Xu took a fancy to his sword. Ji Zha wanted to give it as a gift, but because he was busy with official business, he privately planned to give it to him on his way back home. But when he returned and passed through Xu State, Xu Jun had died of illness, so Jizha hung his sword in front of Xu Jun's tomb to fulfill his long-cherished wish.
