Introduction to Jiangjun Mountain: Jiangjun Mountain and Lion Mountain opposite are two mountains facing each other. The mountain fork in the middle is a pass with dangerous terrain. It was the passage into Lin'an in ancient times. Eight hundred years ago, Jin Wushu led his troops to attack After arriving at Bianliang in Kaifeng, the capital, and heading south, Kang Wang Zhao Gou fled to Lin'an (Hangzhou) to establish a new Kyoto. The general responsible for guarding the pass fought hard with the Jin soldiers for seven days and seven nights and finally failed. He and the remaining soldiers committed suicide and apologized. Later generations commemorated this event. The general's loyalty and patriotism led him to call this mountain Jiangjun Mountain.
There is a sword-sharpening stone on Jiangjun Mountain, covering an area of ​​seven or eight square meters. It is flat and smooth with numerous knife marks on the surface. It was the place where the general sharpened his swords and trained his troops. It was listed as the No. 10 New Scenery in Shuangxi. The three scenes are "The general sharpens his sword".
