Introduction to Zongze: Zongze (1060-1128), courtesy name Rulin, was a famous official who fought against the Jin Dynasty at the end of the Northern Song Dynasty and the beginning of the Southern Song Dynasty. He wrote to Emperor Gaozong and Zhao Gou more than 20 times, urging the return of the capital Tokyo and formulating a strategy to recover the Central Plains, but none of them was adopted. Because his ambition was difficult to achieve, he became ill from worry and anger, and died three times before his death: "Cross the river". He is the author of "Zong Zhong Bian Gong Ji" handed down to the world. The "Zongze Tokyo Defense War" was an important battle between the two Song Dynasties in which the army and people of the Song Dynasty, led by Zongze and other anti-war generals, resisted the invasion of the Jin army and defended the capital Kaifeng.
